A submarine was cruising at 180 feet below sea level (–180). Then it dove to 315 feet below sea level (–315). Use an integer to describe, in feet, the change in the submarine’s depths.

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

d. you cannot tell because there are no values shown.
