Answer:
Step-by-step explanation:
We'll use the slope formula as soon as we figure out the coordinates to plug into it! At x = -4, the y value there is 4; the coordinate is (-4, 4). At x = 1, the y value there is -1; the coordinate is (1, -1). Plugging into the slope formula:
![m=\frac{-1-4}{1-(-4)}=\frac{-5}{5}=-1](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-1-4%7D%7B1-%28-4%29%7D%3D%5Cfrac%7B-5%7D%7B5%7D%3D-1)
If you didn't pick up this, the "average rate of change" is the same exact thing as the slope. It's -1.
√96 / 8
= √12
= √4×3
= √4√3
= 2√3
