The interpretation from the y-intercept is that the cheetah's speed is 0 meters/second when it starts running.
The point (3.0, 12) on the graph can be interpreted as the cheetah's speed being 12 meters/second after 3 seconds of running.
The output value of this graph when the input value is 5.0 is 20 meters/second.
No, the graph does not have a constant rate of change.
