An airplane is flying at an altitude of 4000 feet and descends at a rate of 200 feet per min. Determine whether the altitude is proportional to the # of min.

5 answers

proportional means y = m x
linear means y = m x + b

because of the 4000 feet, this is of form
y = -200 x + 4000

which is linear but not proportional
