donte ordered the plans shown to build a skateboard ramp. each unit represents one foot. he wants to keep the same slope of the ramp and extend the base of the triangle three feet. how tall will the ramp be

Step-by-step explanation:

Note that (0,0) and (3,1) are points on the ramp.

slope of ramp = (1-0)/(3-0) = ⅓

equation of ramp: y = ⅓x

If the base of triangle is extended to 9 ft, the height of the ramp will be ⅓·9 = 3 ft
