A skydiver parachutes to the ground. The height y (in feet) of the skydiver after x seconds is
y=-10x+3000
Find and interpret the slope and y-intercept.
The slope is -10 and means the skydiver is falling at a rate of 10 feet per second.
The y-intercept is 3000 and means the skydiver starts at a height of 3000 feet.
