The depth of the submarine is 50 feet below sea level when it starts to descend at the rate of 10.5 ft/s. It dives at that rate for 5 seconds. You want to model this descent with a linear equation. Determine the slipe and the y-intercept. part a
the slope is: ___, ___
the y-intercept is: ___, ___
a. initial depth of the submarine
b. rate of descent
c. 50 ft
d. 10.5 ft/s
e. 5 seconds

part b
Write the equation in slope-intercept form for the depth of the submarine, y, in feet, below sea level over time, x, in seconds.
