Question

A plane is 24,000 feet above sea

level and 60 miles from the airport.
It flies a straight path until it is
18,000 feet above sea level when
it is 72 miles from the airport. What
is the slope of the plane's path?
A-500
B -0.002
C 0.02
D 42.3

Answer 1

BAnswer: B

Explanation:

Answer 2

A. -500

Explanation:

Find the slope using rise over run (change in y / change in x)

Find the change in the y values (height of the plane):

24,000 - 18,000

= 6,000

Find the change in the x values (miles from the airport)

(60 - 72)

= -12

Divide 6000 by -12:

6000/-12

= -500

So, the slope of the plane's path is A. -500
