An airplane 30,000 feet above the ground begins descending at the rate of 2000 feet per minute. Assume the plane continues at the same rate of descent. The plane’s height and minutes above the ground are related to each other. Identify the variables in this situation: x= y=

What is the given information in this problem (find all that apply)?

y-intercept: slope: Equation:

What is the altitude of the plane after 5 minutes?

Group of answer choices

y-intercept = 2000

Altitude after 5 minutes: 20,000 feet

x = minutes

slope = 15

Altitude after 5 minutes: 29,925 feet

y-intercept = 30000

Equation: y = -2000x + 30000

slope = -2000

x = height

y-intercept = 0

y = minutes

y = height

Equation: y = -15x + 30000
