The height of an airplane is 7480ft at 9:06 A.M. and is 7035ft at 9:11 A.M. It's height is changing at a constant rate.
the rate of descent = 89 ft /minute
At 9.00 it was at a height of 7480+6*89=8014 feet

A. Write an equation that gives the height of the plane(h) x minutes after 9:00 A.M.
h(t)= 8014-89t where t is in minutes
B. What is the slope? Explain its meaning(Include units).
Rise/run is the slope
89/1
=89 ft/minute

C What is the vertical intercept? Explain its meaning.
...
vertical intercept is the y value when x is =0
In this case it is the height at t= 0, height at 9.00 AM
