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 = 1,200x + 2705, where y is in feet and x is the time in minutes since take-off. Find and interpret the slope and y-intercept. A. m=1,200; The altitude of the airplane increases 1,200 feet every minute. b = 2705; The altitude of the airport where the airplane took-off is 2705 feet above sea level. B. m=2705; The minutes since take-off increases 2705 for every foot of altitude. b = 1,200; It takes 1,200 minutes for the plane to get to the altitude of the airport from sea level. OC. m=1,200; The minutes since take-off increases 1,200 for every foot of altitude. b= 2705; It takes 2705 minutes for the plane to get to the altitude of the airport from sea level. D. m=2705; The altitude of the airplane increases 2705 feet every minute. b= 2705; The altitude of the airport where the airplane took-off is 1,200 feet above sea level.

Question
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 = 1,200x + 2705, where y is in feet and x is the time in minutes since take-off. Find and interpret the slope and y-intercept.
A. m=1,200; The altitude of the airplane increases 1,200 feet every minute. b = 2705; The altitude of the airport where
the airplane took-off is 2705 feet above sea level.
B. m=2705; The minutes since take-off increases 2705 for every foot of altitude. b = 1,200; It takes 1,200 minutes for
the plane to get to the altitude of the airport from sea level.
OC. m=1,200; The minutes since take-off increases 1,200 for every foot of altitude. b= 2705; It takes 2705 minutes for
the plane to get to the altitude of the airport from sea level.
D. m= 2705; The altitude of the airplane increases 2705 feet every minute. b = 2705; The altitude of the airport where
the airplane took-off is 1,200 feet above sea level.
