List the point of of y - 9 = -3(x + 4)
Explanation
The given equation is in the form of y - 9 = -3(x + 4), which is the equation of a straight line in slope-intercept form. The equation represents a line with a slope of -3 and a y-intercept of 9. Since the equation does not have any x-term, the value of x can be any real number. Therefore, the line passes through all points with x-coordinate equal to -4 and y-coordinate equal to 9. Thus, the correct answer is (-4, 9), (-4,9).Rate this question:

List the point of y + 7 = 8(x - 3)
Explanation
The given equation is in the form y + 7 = 8(x - 3), which represents a linear equation. The answer (3, -7) indicates that when x is equal to 3, y is equal to -7. This means that the point (3, -7) satisfies the equation and lies on the graph of the equation. Therefore, (3, -7) is a valid point for the given equation.Rate this question:

List the slope of y - 4 = -6x
Explanation
The slope of a linear equation can be determined by the coefficient of the x-term. In this equation, y - 4 = -6x, the coefficient of x is -6. Therefore, the slope is -6. The other expressions mentioned, m = -6 and m=-6, are just alternative ways of representing the slope of -6.Rate this question:

Find the slope of y + 13 = x
Explanation
The equation given is in the form y + 13 = x + 1. By rearranging the equation, we can see that y = x - 12. The slope of this equation is 1, which means that for every increase of 1 in the x-coordinate, the y-coordinate will increase by 1 as well. Therefore, the slope of y + 13 = x + 1 is 1.Rate this question:

Find the slope of y = 3/5 (x + 2)
Explanation
The given equation is in the form y = mx + b, where m represents the slope of the line. In this case, the equation is y = 3/5 (x + 2), which can be rewritten as y = 3/5x + 6/5. Therefore, the slope of the line is 3/5.Rate this question:

Find the point of y = 3/5 (x + 2)
Explanation
The given answer, (-2, 0), (-2,0), is the correct point for the equation y = 3/5 (x + 2). This means that when x is equal to -2, y is equal to 0. The equation represents a linear relationship between x and y, where the slope is 3/5 and the y-intercept is 2. Therefore, when x is -2, plugging it into the equation gives y = 3/5 (-2 + 2) = 3/5 * 0 = 0. This confirms that the point (-2, 0) is on the line represented by the equation.Rate this question:

List the slope and a point on the line from the equation:y - 2 = 3/5 ( x + 9)
-
M = 3/5 (-2, 9)
-
M = -3/5 (-2, 9)
-
M = 3/5 (-9, 2)
-
M = 3/5 (9, -2)
Correct Answer
A. M = 3/5 (-9, 2)Explanation
The equation of the line is given in the form y - 2 = 3/5 (x + 9), which is in slope-intercept form y = mx + b. The slope (m) is 3/5, which is the coefficient of x. The point (-9, 2) is on the line because when we substitute x = -9 into the equation, we get y = 2. Therefore, the correct answer is m = 3/5 (-9, 2).Rate this question:

List the slope and a point on the line from the equation:y + 8 = 4 ( x - 7)
-
M = 4 (7, -8)
-
M = 4 (-7, 8)
-
M = 4 (8, -7)
-
M = 4 (-8, 7)
Correct Answer
A. M = 4 (7, -8)Explanation
The equation given is in slope-intercept form, y = mx + b, where m is the slope of the line. In this equation, the slope is 4. The point (7, -8) is given in the equation, and it satisfies the equation when substituted into it. Therefore, the correct answer is m = 4 (7, -8).Rate this question:

What is the equation in point slope form given the slope is 6 and goes through the point (-4,-16).
-
y - 16. = 6(x - 4)
-
Y + 16 = 6( x +4)
-
Y - 4 = 6(x - 16)
-
Y + 4 = 6(x +16)
Correct Answer
A. Y + 16 = 6( x +4)Explanation
The equation in point-slope form is y + 16 = 6(x + 4). This is because the point-slope form equation is y - y₁ = m(x - x₁), where (x₁, y₁) is the given point and m is the given slope. In this case, the given point is (-4, -16) and the slope is 6. Plugging in these values into the equation gives y + 16 = 6(x + 4).Rate this question:
