The predicted value of Y, given that X and Y have a correlation of .6 and X has a particular value of 1, is .6. This is because in a simple linear regression with standardized scores (Z scores), the regression coefficient (slope) is equal to the correlation coefficient. Thus, if X increases by 1 standard deviation, Y is predicted to increase by .6 standard deviations, the correlation coefficient.
