Answer

Answer:

(0, 80), (15, 10)

Explanation:

Step1: Recall average - rate - of - change formula

The average rate of change of a function $y = f(x)$ from $x = a$ to $x = b$ is $\frac{f(b)-f(a)}{b - a}$. Here, we want the average rate of change from the start ($x = 0$) to $x=15$. So we need the points at $x = 0$ and $x = 15$. The point at $x = 0$ is $(0,80)$ (the starting height) and the point at $x = 15$ is $(15,10)$.
