Part A: make slope-intercept form of equation

We will have variable y for the depth of the submarine after x hours. The start 1,500 will be written - 1,500 because it's below surface of water.

The equation after x hours will be

y = - 1,500 + 52x

y = 52x - 1,500

Part B: Find the depth after two hours

Change variable x with 2

y = 52x - 1,500

y = 52 (2) - 1,500

y = 104 - 1,500

y = - 1,396

Negative means it's below surface
