Answer:
The correct answer would be A. 15/4.
Step-by-step explanation:
Slope is equal to the change in <em>y </em>over the change in x<em>, </em>or rise over run.
m = change in y/change in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).
m = y2 - y1/x2 - x1
Substitute in the values of x and y into the equation to find the slope.
m = 5 - (- 10)/- 1 - (- 5)
Simplify.
m = 15/4
