Answer: x=-4

Step-by-step explanation: Slope is equal to the change in y over the change in x, 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=-2-(2)/-1-(-2)

Simplify. m=-4
