After descending for 8 minutes, an airplane is at an altitude of 24800 feet. After descending for 20 minutes, the plane's altitude is 12800 feet. Assuming a linear function, write an equation in the form a(t) = mt+b that shows the altitude, a, after t minutes of descent. Provide your answer below: a(t) =
