use an integer to represent the change in the airplanes height.an airplane descends 5,000 feet.

-5,000

To represent the change in the airplane's height as an integer, we can use a negative number since the airplane descends.

In this case, the airplane descends 5,000 feet, so we can represent it as -5000.

Keep in mind that if the airplane ascends, we would use a positive number to represent the change in height.
