A scuba diver dove from the surface of the ocean to an elevation of -89 9/10 feet at a rate of -21.2 feet per minute. After spending 14 minutes at that elevation the driver ascended to an elevation of -38 9/10 feet. The total time of the five so far was 21 1/8 minutes. What was the rate of change in the divers elevation during ascent?

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

x-3y=4

step-by-step e

it would open into a square depending on the type of envelope i’m not sure about the second part
