The answer would be r
Reason:
Covariance and Variance don't change on adding constants (for reason refer to variance Week 3). For Covariance the reason is similar because on x+b-{mean(x)+b}. Now for xi and yi, the correlation is r. For the new one it would be, b x Cov(x) *d Cov(y)/ (b*s(x) x d*s(y)). So bd cancels off.
