Suppose we have a sample of 50 observations on x and y, and sd of x and sd of y are both positive. We look at the scatterplot of x against y, and then we draw two lines in the scatterplot. Using Line #1, residuals are calculated and they do not sum to 0. Using Line #2, residuals are calculated and they do sum to 0.

Line #1 ____ the OLS regression line of x on y, and Line #2 ____ the OLS regression line of  x on y.
