Question

the scatter plot and line of best fit below show the length of 11 peoples femur (the long leg bone in the thigh) and their height in centimeters. what is the meaning of the x - value on the line when y = 150?

Explanation:

The scatter plot has the x - axis representing femur length (in centimeters) and the y - axis representing height (in centimeters). The line of best fit models the relationship between femur length and height. When \(y = 150\) (height is 150 centimeters), the \(x\) - value on the line of best fit represents the predicted femur length (in centimeters) for a person whose height is 150 centimeters, based on the linear relationship established by the line of best fit from the data of 11 people's femur lengths and heights.

Answer:

The \(x\) - value on the line when \(y = 150\) represents the predicted femur length (in centimeters) for a person with a height of 150 centimeters, according to the linear relationship (line of best fit) between femur length and height from the given data.
