Answer

Explanation:

Step1: Identify the formula for average rate of change

The formula for the average rate of change of a function $y = f(x)$ from $x = a$ to $x = b$ is $\frac{f(b)-f(a)}{b - a}$.

Step2: Determine the points for $x = 10$ and $x = 15$

From the graph, when $x = 10$, $y = 20$ and when $x = 15$, $y = 10$.

Step3: Calculate the average rate of change

Using the formula $\frac{f(15)-f(10)}{15 - 10}=\frac{10 - 20}{15 - 10}=\frac{- 10}{5}=-2$.
