Answer #1

The least squares regression line is of the same form as any line...has slope and intercept. To indicate that this is a calculated line we will change from "y=" to "y hat =". It can be shown that the slope (b) = r (sy/sx) where r is the correlation factor and s are the standard deviations for both x and y
