Aramp with a constant incline is made to connect a driveway to a front door. at a point 4 feet from the driveway, the height of the ramp is 12 inches. at a point 6 feet from the driveway, the height of the ramp is 18 inches. what is the rate of change of the ramp’s incline? answer is 3

Rate of change of the ramp's incline is 3.

Step-by-step explanation:

Since the points on ramp F and G have the coordinates (4, 12) and (6, 18)

Now the slope of the ramp passing through two points will be the rate of change of the ramp's incline.

Slope =

         =

         =

Therefore, rate of change of the ramp's incline is 3.

the answer to the question is a  

it has the same slope and the same y-intercept.
