Y = -9x - 10
The dolphin is diving 9 feet per second so the rate of change is -9.
It's also 10 feet below sea level which makes the y-intercept -10
Hope this helped!

What is an equation of the line that passes through the point(2,−2) and is parallel to the line 5x-2y=4
mixer [17]

Answer:

y = 5/2x - 7

Slope = 5/2

Point (2,-2)

y-intercept: -2 - (5/2)(2) = -2 - 5
