Question

Bill is riding his bike. The number of revolutions (turns) his wheels make varies directly with the distance he travels. See the graph below.

Answer 1

a) How far does he travel per revolution

We can see that from 4 to 6 revolutions, he traveled 48-32 = 16 feet, then it was 16 feet in 2revolutions or 8 feet per revolution

Answer: 8

b) slope

`m=(y2-y1)/(x2-x1)=(6-4)/(48-32)=(2)/(16)=(1)/(8)`

Answer: 1/8
