Find correlation coefficient?

the least squares best fit line for the number of years in college X and the income level Y is Y=11.9+ 3.46X

Given that the standard errors of X and Y are Sx=1.8 and Sy = 7.2, what is the correlation coefficient?

Look in your notes or in your textbook for any formulas relating to the slope of a least squares regression line.
