Answer 1

upward 5,000 miles for every 20,000 miles in horizontal distance.
upward = positive change in y value
horizontal distance = x
a) What is the rate of change? change in y / change in x
= 5000/20000 = 0.25
recently taken off from the airport or if it is getting ready to land? Explain.
oops already answered is currently traveling upward
