Question

A bunny hop is a bike trick in which the rider brings both tires off the ground without using a ramp. The table shows the height y (in inches) of a bunny hop on a bike that weighs x pounds.

part b.
Write a linear function that relates the height of a bunny hop to the weight of the bike.

y=

Answer 1

We use two points to calculate the slope:
slope = (9.8 - 10.2) / (21 - 19)
slope = -0.2

The form:
y = mx + c
9.8 = -0.2(21) + c
c = 14

The equation is:
y = -0.2x + 14
