correlation coefficient

[missyc8]

how would i find the correlation coefficient given the following information...i do not need the answer, just how to find it!

regression line y = 10 - 1.5(x) and a coefficient of determination of 0.61.


Thanks!

If the correlation coefficient lies between 0 and 1 and the correlation coefficent squared
gives the coefficient of determination, take the positive square root of the coefficient of determination.
