Question

theres a roughly linear relationship between the length of someones femur (the long leg - bone in your thigh) and their expected height, as expressed in the graph below. what is the meaning of the y - value when x = 55? the graph has a y - axis labeled expected height (centimeters) with values from 60 to 210 and an x - axis labeled femur length (centimeters) with values from 0 to 80. a line is plotted on the graph showing the relationship between femur length and expected height.

Explanation:

Step1: Identify x and y meanings

x is femur length (cm), y is expected height (cm).

Step2: Interpret x=55

When femur length (x) is 55 cm, y - value is expected height for that femur length.

Answer:

The y - value when \( x = 55 \) represents the expected height (in centimeters) of a person whose femur length is 55 centimeters.
