Answer 1

The answer is -80

Explanation:

I took the quiz

Answer 2

The answer is -80

Explanation:

The average rate of change is also the slope from the endpoints. The two points are (0,500) to (5, 100). To find the average rate of change between those points, use the formula: change of y over the change of x.

`(y2-y1)/(x2-x1)`

`(100-500)/(5-0) = (-400)/(5)  =-80`
