For a biology project, you measure the weight in grams and the tail length in millimeters (mm) of a group of mice.

For a biology project, you measure the weight in grams and the tail length in millimeters (mm) of a group of mice. The equation of the least-squares line for predicting tail length l from weight w is
l = 21 + 8 w


Now, if you measured the tail length in centimeters instead of millimeters, what would be the slope of the regression line? (There are 10 millimeters in a centimeter.)
