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 = 1100x + 2295, 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.
A. m = 2295; The minutes since take-off increases 2295 for every foot of altitude. 
The minutes that the plane takes to get to the altitude of the airport from sea level.
B. m = 1100; The altitude of the airplane increases 1100 feet every minute. y-intercept: 2295; The altitude of the airport where the airplane took-off is 2295 feet above sea level.
C. m = 2295; The altitude of the airplane increases 2295 feet every minute. y-intercept: 2295; The altitude of the airport where the airplane took-off is 1100 feet above sea level.
D. m = 1100; The minutes since take-off increases 1100 for every foot of altitude.
