Question

A submarine is descending to examine the seafloor 2,100 feet below the surface. it takes the submarine 2 hours to make this descent. Write an equation to

represent the relationship between the submarine's elevation and time.

Answer 1

Explanation:

x = time

y = elevation

At x = 0 , y = 0

It takes the submarine 2 hours to make descent of 2100 ft

=> x = 2 , y = - 2100

Slope = ( -2100 - 0)/(2 - 0) = -1050

y - 0 = -1050 ( x -0)

=> y = -1050x

1050x + y = 0

represent the relationship between the submarine's elevation and time.
