Solve the problem.The altitude above sea level of an airplane just after taking off from an airport on a high plateau is given by the equation y = 1200x + 2060, where y is in feet and x is the time in minutes since take-off. Complete the given table and find and interpret the slope.
A. m = 1200; The altitude of the airplane increases 1200 feet every minute.
B. m = 2060; The altitude of the airplane increases 2060 feet every minute.
C. m = 2060; The minutes since take-off increases 1200 for every foot of altitude.
D. m = 2060; The minutes since take-off increases 2060 for every foot of altitude.
