Answer:
Explanation:
1. Use this
to find the average rate of change
2. Average rate of change =

3.
and
(To find these you will need to look at the points on the graph. So the points (8,-4) and (6,-10))
4. Replace -4 to f(8) and -10 to f(6)
5. So it will look like
![(-4-(-10))/(8-6)](https://img.qammunity.org/2021/formulas/mathematics/high-school/lnjwjjw5j190kbq9p6mj4a9bu1e7js918k.png)
