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 linear function y = 900x + 3257, where y is in feet and x is the time in minutes since take-off. Find and interpret the slope and y-intercept of the linear equation.

Question

A. m = 900; The altitude of the airplane increases 900 feet every minute. y-intercept: 3257; The altitude of the airport where the airplane took-off is 3257 feet above sea level.
B. m = 3257; The altitude of the airplane increases 3257 feet every minute. y-intercept: 3257; The altitude of the airport where the airplane took-off is 900 feet above sea level.
C. m = 900; The minutes since take-off increases 900 for every foot of altitude.  ; The minutes that the plane takes to get to the altitude of the airport from sea level.
D. m = 3257; The minutes since take-off increases 3257 for every foot of altitude.   The minutes that the plane takes to get to the altitude of the airport from sea level.
