A, the x values don’t repeat
Hello!
Find the coordinate where x = -1:
At x = -1, y = 1, so the coordinate is (-1, 1).
Find the coordinate where x = 2:
At x = 2, y = -2, so the coordinate is (2, -2).
Find the rate of change between the points using the slope formula:
![slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}](https://tex.z-dn.net/?f=slope%20%3D%20%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D)
Plug in the coordinates above:
![slope = \frac{-2-1}{2-(-1)}](https://tex.z-dn.net/?f=slope%20%3D%20%5Cfrac%7B-2-1%7D%7B2-%28-1%29%7D)
Simplify:
Thus, the rate of change between the points is -1.
Answer:
