A small aircraft takes off from the ground. The height of the aircraft increases by 1,000 feet for every minute that has passed since the aircraft left the ground.
Which function best represents the height of the aircraft in feet, as a function of time in minutes?

f(x ) = 1000x
y= mx+b
b= 0
The slope m (feet for every minute) (y/x) (variation of y with respect to x)
