Question

answer
the expected height for someone with a femur length of 65 centimeters.
the change in expected height for every one additional centimeter of femur length.
the femur length for someone with an expected height of 2.5 centimeters.
the change in expected femur length for every one additional centimeter of height.

Explanation:

Step1: Identify the nature of the line graph

The graph shows expected height (y - axis) as a function of femur length (x - axis). The slope of a line in a linear relationship $y=mx + b$ represents the change in y for a unit - change in x.

Step2: Determine the meaning of the slope

In this context, y is the expected height and x is the femur length. So, the slope of the line represents the change in expected height for every one additional centimeter of femur length.

Answer:

The change in expected height for every one additional centimeter of femur length.
