In a data set with a strong linear correlation, the points in the scatter plot approximate a line. Turn on show least-squares fit line. The least-squares fit line is the best-fit line, or the line that most closely "fits" the shape of the data.

A.When r=1, how are the points in the scatter plot related to the least-squares fit line?

B.Slowly decrease r. How does this affect where the points are in relation to the line ?
