This quiz will test your knowledge of slope.

1. Which direction does a line slope if the slope is negative?

It slopes up

It slopes down

It is a horizontal line

It is a vertical line

When the slope of a line is negative, it means that the line is decreasing as it moves from left to right. In other words, the line is sloping downwards. This can be visualized as a line that starts at a higher point on the y-axis and gradually decreases as it moves towards higher values on the x-axis. Therefore, the correct answer is "it slopes down."

Explanation

When the slope of a line is negative, it means that the line is decreasing as it moves from left to right. In other words, the line is sloping downwards. This can be visualized as a line that starts at a higher point on the y-axis and gradually decreases as it moves towards higher values on the x-axis. Therefore, the correct answer is "it slopes down."

2.

What is the change in y?

5

3

2

-2

The change in y is 3 because it is the difference between the last given value of y (2) and the previous value of y (5).

Explanation

The change in y is 3 because it is the difference between the last given value of y (2) and the previous value of y (5).

3. What is slope?

A measure of the steepness of a line; compares the vertical distance to the horizontal distance.

A measure of how long the line is

The horizontal change compared to the vertical change

Change in x over a change in y

Slope is a measure of the steepness of a line and is determined by comparing the vertical distance to the horizontal distance. It indicates how much the line is rising or falling as it moves horizontally. The greater the slope, the steeper the line. The correct answer accurately describes slope as a measure of steepness and the comparison between vertical and horizontal distances.

Explanation

Slope is a measure of the steepness of a line and is determined by comparing the vertical distance to the horizontal distance. It indicates how much the line is rising or falling as it moves horizontally. The greater the slope, the steeper the line. The correct answer accurately describes slope as a measure of steepness and the comparison between vertical and horizontal distances.

4. Which is true about the slope of a line?

It is constant, the same slope for the whole line

It can change throughout the line

The correct answer is "it is constant, the same slope for the whole line." This means that the slope of a line does not change as you move along the line. It remains constant and consistent throughout the entire line.

Explanation

The correct answer is "it is constant, the same slope for the whole line." This means that the slope of a line does not change as you move along the line. It remains constant and consistent throughout the entire line.

5. Which line is steeper?

Y = 5x

Y = .5x

The bigger the number the steeper the line.

Explanation

The bigger the number the steeper the line.

6. Which line is steeper?

Y = 20x

Y = 15x

The bigger the number the steeper the line.

Explanation

The bigger the number the steeper the line.

7.

What is the change in x?

5

3

2

-2

not-available-via-ai

Explanation

not-available-via-ai

8. What is the y-intercept (starting value) of the line y = -3x - 7?

3

7

-7

-3

y-intercept is your b value or always the number that follows the x.

Explanation

y-intercept is your b value or always the number that follows the x.

9. What is a trend line?

A line that intersects every point on the graph.

A line that represents a set of data but does not intersect all the points.

A trend line is a line that represents a set of data but does not intersect all the points. It is used to show the general direction or trend of the data and is often used in statistical analysis to make predictions or identify patterns. The line is drawn in a way that minimizes the distance between the line and the data points, providing a visual representation of the relationship between the variables being studied.

10.

What is the slope of the line?

-1

-2

2

-3

The slope of a line represents the rate at which the line is rising or falling. In this case, the correct answer is -2, which means that for every increase of 1 unit on the x-axis, the line will decrease by 2 units on the y-axis. The negative sign indicates that the line is sloping downwards from left to right.
