10.9Suppose that we know that the correlation between two variables named X and Y is .56. What would you expect would happen to the correlation if we subtracted 10 points from every x score?

The correlation would not change the relationship between X and Y.However, the intercept would change.

With regard to Exercise 10.9, suppose that the mean of X was 15.6 and the mean of Y was 23.8.What would happen to the slope and intercept if we subtracted 10 points from every Y?
