Answer

Answer:

-4.67

Explanation:

Step1: Recall average rate - of - change formula

The formula for the average rate of change of a function $y = f(x)$ from $x_1$ to $x_2$ is $\frac{f(x_2)-f(x_1)}{x_2 - x_1}$. Here, the two points are $(0,80)$ and $(15,10)$. Let $(x_1,y_1)=(0,80)$ and $(x_2,y_2)=(15,10)$.

Step2: Substitute values into formula

$\frac{y_2 - y_1}{x_2 - x_1}=\frac{10 - 80}{15-0}$.

Step3: Calculate the result

$\frac{10 - 80}{15-0}=\frac{-70}{15}\approx - 4.67$.
