Question

An airplane 30,000 ft above the ground begins descending at a rate of 2,000 ft per minute. Write an slope-intercept form that models this situation. Find the altitude of the plane after 5 minutes.

Answer 1

2000ft x 5mins = 10000
^^^ 2000+2000+2000+2000+2000= 10000
1 min. 2min. 3min. 4min. 5min.

Altitude of plane = 30,000-10,000 = 20,000 ft

For me to create a slope intercept form which models this situation I have to send a picture give me a sec
