Question

Mel slides down waterslide A, and Victor slides down waterslide B. After 2 seconds, Mel was 50 feet in the air, and after 5 seconds, she was 35 feet in the air. After 1 second, Victor was 60 feet in the air, and after 4 seconds, he was 50 feet in the air. Who was descending at a faster rate?
Mel: (2, 50) and (5, 35)

Victor: (1, 60) and (4, 50)

Mel’s rate of change is____.That means that her height in the air decreases _____ feet every second.

Victor’s rate of change is _____ . That means that his height in the air decreases _____ feet every second.

Answer 1

The first thing you should do for this case is to find both slopes by applying the following equation:
 m = ((y2) - (y1)) / ((x2) - (x1))
 Mel: (2, 50) and (5, 35)
 m1 = ((35) - (50)) / ((5) - (2))
 m1 = -5 feet / s
 Victor: (1, 60) and (4, 50)
 m2 = ((50) - (60)) / ((4) - (1))
 m2 = -3.333333333 feet / s
 
 answer:
 Mel was descending at a faster rate
 Mel's rate of change is negative. That means that your height in the air decreases 5 feet every second.
 Victor's rate of change is negative. That means that his height in the air decreases 3.33 feet every second.
