Question

A simple regression produces the regression equation Y-bar = 5X + 7.
a. If we add 2 to all the X values in the data (and keep the Y values the same as the original), what will the new regression equation be?
b. If we add 2 to all the Y values in the data (and keep the X values the same as the original), what will the new regression equation be?
c. If we multiply all the X values in the data by 2 (and keep the Y values the same as the original), what will the new regression equation be?
d. If we multiply all the Y values in the data by 2 (and keep the X values the same as the original), what will the new regression equation be?
