### In the coordinate plane below, quadrilateral ABCD is reflected over the y-axis to form quadrilateral EFGH.Which angle is angle B congruent to?

• A.

E

• B.

F

• C.

G

• D.

H

B. F
Explanation
When a figure is reflected over the y-axis, the x-coordinates of the points remain the same, but the y-coordinates change sign. In this case, angle B is a vertex of quadrilateral ABCD, and when it is reflected over the y-axis, it becomes angle F in quadrilateral EFGH. Therefore, angle B is congruent to angle F.

### Below is the graph of the linear equation y= -3x+4.what are the slope and y-intercept of this graph?

• A.

Slope of -3, y-intercept of 4

• B.

Slope of 1/3, y-intercept of -4

• C.

Slope of -3, y-intercept of -4

• D.

Slope of -1/3, y-intercept of 4

A. Slope of -3, y-intercept of 4
Explanation
The slope of a linear equation represents the rate of change of the dependent variable (y) with respect to the independent variable (x). In this case, the slope is -3, indicating that for every 1 unit increase in x, y decreases by 3 units. The y-intercept represents the value of y when x is equal to 0. In this case, the y-intercept is 4, meaning that the graph intersects the y-axis at the point (0, 4). Therefore, the correct answer is slope of -3, y-intercept of 4.

### Point K (2,1) and J(-4,-7) are shown on the coordinate plane below.What is the distance between point K and J?

• A.

4 units

• B.

8 units

• C.

10 units

• D.

16 units

C. 10 units
Explanation
The distance between two points in a coordinate plane can be found using the distance formula, which is derived from the Pythagorean theorem. The formula is: distance = sqrt((x2-x1)^2 + (y2-y1)^2). In this case, the x-coordinates of K and J are 2 and -4 respectively, and the y-coordinates are 1 and -7 respectively. Plugging these values into the formula, we get: distance = sqrt(((-4)-(2))^2 + ((-7)-(1))^2) = sqrt((-6)^2 + (-8)^2) = sqrt(36 + 64) = sqrt(100) = 10 units. Therefore, the distance between point K and J is 10 units.

• A.

A

• B.

B

• C.

C

• D.

D

A. A
Explanation
Graph A is the most likely scatter plot that Quincy created because it shows a random distribution of points with no clear pattern or trend. In a scatter plot, the points represent individual data points, and in this case, the points are scattered across the graph without any obvious relationship between age and height. Graphs B, C, and D show either a positive or negative correlation between age and height, which is not indicated in the question.

### Two points on the graph of a line are (-2,6) and (1,-2). what is the rate of change of the line?***Answers below are fraction

• A.

-4/3

• B.

4/3

• C.

-3/4

• D.

3/4

A. -4/3
Explanation
The rate of change of a line can be found by calculating the difference in the y-coordinates divided by the difference in the x-coordinates of two points on the line. In this case, the difference in the y-coordinates is -2 - 6 = -8, and the difference in the x-coordinates is 1 - (-2) = 3. Therefore, the rate of change is -8/3, which can be simplified to -4/3.

### Marcela has the lid from a can of cherries that her friend Lily used to make a pie. The radius of the lid measures 1.5 inches and the formula for the volume of a cylinder is V= (pi)r2h. If the recipe calls for cherries that fill a 22-cubic inch can, which is the height to the nearest inch of the can of cherries needed to make a pie?

• A.

1.5 in

• B.

3 in

• C.

4 in

• D.

6.75 in

B. 3 in
Explanation
The formula for the volume of a cylinder is V= (pi)r^2h. Since the radius of the lid is given as 1.5 inches, we can substitute this value into the formula. We are also given that the volume of the can of cherries needed is 22 cubic inches. By rearranging the formula to solve for h, we can find the height. Plugging in the values, we have 22 = (pi)(1.5^2)h. Solving for h gives us h ≈ 3 inches. Therefore, the height of the can of cherries needed to make a pie is 3 inches.

### What is the slope of the line that passes through the points (-7, -6) and (3,0)?***The numbers below are fractions

• A.

-8/3

• B.

-2

• C.

-5/3

• D.

3/5

D. 3/5
Explanation
To find the slope of a line passing through two points, we can use the formula (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points. In this case, the coordinates are (-7, -6) and (3, 0). Plugging these values into the formula, we get (0 - (-6)) / (3 - (-7)), which simplifies to 6 / 10 or 3/5. Therefore, the slope of the line passing through these points is 3/5.

### On the coordinate plane below, the figure DART is dilated by a factor of 2.D(-3,4) A( 4, 3)R( 4, -3)T( -3, -4)

• A.

A

• B.

B

• C.

A. A
Explanation
The figure DART is dilated by a factor of 2, which means that each point in the figure is multiplied by 2 in both the x and y coordinates. Therefore, the new coordinates for point D would be (-3*2, 4*2) = (-6, 8). Comparing this with the given answer choices, we can see that the new coordinates (-6, 8) match with point A. Therefore, the correct answer is A.

### Ray tells his friend Danny that he can bicycle 5 miles to the local pool in 20 minutes. Danny then shows Ray a graph of his bicycle ride to the local YMCA, pictured below.

• A.

Ray, because he bicycles 15 miles an hour and Danny bicycles 12 miles an hour.

• B.

Ray, because he bicycles 20 miles an hour and Danny bicycles 12 miles an hour.

• C.

Danny, because he bicycles 10 miles an hour and Ray bicycles 5 miles an hour.

• D.

Danny, because he bicycles 5 miles an hour and Ray bicycles 4 miles an hour.

A. Ray, because he bicycles 15 miles an hour and Danny bicycles 12 miles an hour.
Explanation
Based on the given information, Ray claims that he can bicycle 5 miles to the local pool in 20 minutes. Looking at the graph provided by Danny, it shows that Ray's ride to the local YMCA took 20 minutes as well. Since the distance is the same for both rides, but Ray's ride took the same amount of time at a faster speed, it can be concluded that Ray bicycles at a faster speed than Danny. Therefore, the correct answer is Ray, because he bicycles 15 miles an hour and Danny bicycles 12 miles an hour.

### Solve for y:11(y-2)+3y=-7y+14***The following are fractions

• A.

7/12

• B.

12/7

• C.

14

• D.

21

B. 12/7
Explanation
To solve the equation, we need to simplify both sides. First, distribute 11 to (y-2), which gives us 11y - 22. Then, combine like terms by adding 3y and 7y on the right side, which gives us 10y. Simplifying further, we have 11y + 10y - 22 = 14. Combining like terms again, we get 21y - 22 = 14. To isolate y, we add 22 to both sides, resulting in 21y = 36. Finally, we divide both sides by 21, giving us y = 36/21, which simplifies to 12/7. Therefore, the answer is 12/7.

### Quadrilateral PQRS is transformed to create quadrilateral P'Q'R'S'.Which of the following best describes the transformation from PQRS to ​P'Q'R'S' below?

• A.

Reflection over the y-axis

• B.

Rotation 90 clockwise

• C.

Translation 4 units down

• D.

Reflection over the x-axis

D. Reflection over the x-axis
Explanation
The given answer, "reflection over the x-axis," best describes the transformation from PQRS to P'Q'R'S'. This is because a reflection over the x-axis would result in the points being mirrored across the x-axis. In other words, any point above the x-axis would be reflected to a point below the x-axis, and vice versa. This transformation would change the orientation of the quadrilateral, flipping it upside down.

### What is the solution to the following system of linear equations?2x-7y=12-2x+6y=-10

• A.

(1,2)

• B.

(2,-1)

• C.

(-1,-2)

• D.

(-2,-1)

C. (-1,-2)
Explanation
The solution to the given system of linear equations can be found by solving the equations simultaneously. By adding the two equations, we can eliminate the x variable and solve for y. The resulting equation is -y = 2, which gives us y = -2. Substituting this value of y into either of the original equations, we can solve for x. Plugging in y = -2 into the first equation, we get 2x - 7(-2) = 12, which simplifies to 2x + 14 = 12. Solving for x, we find x = -1. Therefore, the solution to the system of equations is (-1, -2).
