An airplane at 30,000 feet begins its descent. The plane descends 500 feet per minute. Write an equation in the form y = mx + b to model the height of the plane during its descent. |

Answer» Answer: f = feet above ground R = rate of descent m = MINUTES
f = 30000 - r · m f = 30000 - 20000m
After FIVE minutes:
f = 30000 - 2000(5) f = 30000 - 10000 f = 20000
After five minutes the PLANE is at 10,000. feet |
