Question

The scatter plot and line of best fit below show the length of 12 people's femur (the long leg bone in the thigh) and their height in centimeters. Based on the line of best fit, what would be the predicted height for someone with a femur length of 70 cm?

Answer 1

An expected height of 160.6 centimeters when the femur has a length of 40 centimeters.

Explanation:

The line of best fit makes a prediction. In other words, it tells us what height to expect for any given femur length.

x represents femur length and y represents height, so the y-value on the line when x=40x is the expected height when the femur length is 40 cm.
