The graph shows the side view of a waterslide. dimensions are in feet.

two points on slide:
(0, _) , 40)

Two points on slide are (0, 80), (5, 40).

Step-by-step explanation:

The graph shows the side view of a waterslide and its dimensions are in feet.

First to find (0, ___) and then to find (, 40).

In the first point x-coordinate is 0 and y-coordinate for the corresponding x-coordinate is 80.

In the second point y-coordinate is 40 and the x-coordinate for the corresponding y-coordinate is 5.

So, the two points are (0, 80), (5, 40).

the answer is 99.
