Solve the problem.The speed of a ball dropped from a tower is given by the linear function y = 32x where y is in feet per second and x is the number of seconds since the ball was dropped. Find and interpret the slope and y-intercept of the linear equation.
A. m = 32; The speed of the ball increases 32 feet per second every second. There is no y-intercept to interpret.
B. m = 0; The speed of the ball does not increase as time passes. y-intercept: 32; At time x = 0, the ball has fallen 32 feet.
C. m = 32; The speed of the ball increases 32 feet per second every second. y-intercept: 0; The speed of the ball was 0 the moment it was dropped.
D. m = 32; The speed of the ball is 32 feet per second. y-intercept: 0; When the ball is dropped at x = 0, the ball has fallen 0 feet.
