Question

16. An airplane 30,000 feet above the ground begins descending at a rate of 2,000 feet per minute. Write an equation to model the situation. Find the altitude of the plane after 5 minutes​

Answer 1

Answer:

equation: y=-2,000x+30,000

altitude after five minutes: 20,000

Step-by-step explanation:

y = altitude of the plane

x= slope (the plane descends -2000 feet per min, so the slope is -2000)

the y-intercept is 30,000 as the plane begins at 30000 feet above ground
