Question

question
the scatter plot and line of best fit below show the length of 10 peoples femur (the long leg bone in the thigh) and their height in centimeters. what does the slope of the line represent?

answer
the expected femur length when the height is 1 centimeter.
the change in expected height for every one additional centimeter of femur length.
the change in expected femur length for every one additional centimeter of height.
the expected height when the femur has a length of 1 centimeter.

Explanation:

The line of best fit models the relationship between femur length (x-axis) and height (y-axis). Slope represents the change in the dependent variable (height) per unit change in the independent variable (femur length).

Answer:

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