14. An airplane descends at a constant rate of 2500 feet per minute until it reaches the ground. Just before it begins to descend, the airplane is initially 35,000 feet above the ground. (1.5 notes)
a. Write an equation to represent h, the airplane's height above the ground in feet, based on m, the time
in minutes it spends descending.

Find the solution of system of equation y= x-4 y=4x+2
