Question

After 1 minute, a submarine had descended to −280 feet. After 9 minutes, the submarine had descended to −360 feet. Assuming a linear function, write an equation in the form d(t)=mt+b that shows the depth, d(t), after t minutes.

Answer 1

Answer:

the answer is 640

Step-by-step explanation:

-280-360 = 640

d(t)=-360

= 360*d*t
