which rate of change represents the graph shown
a: -200 feet per minute
b: 15 feet per minute
c: 200 feet per minute
d: -15 feet per minute

D

Explanation:
It cannot be A as the submarine does not do down 200 feet per minute.

It cannot be B or C as the rate of change is positive and the graph shows a negative, declining line indicating that the rate of change is a negative.

Also we take an exact point (40, -600). When we divide -600/40 = -15

Therefore the answer is D
