How to use a Casio fx-85gt for reverse correlation coefficient!!!

Hi all

I'm at my wit's end.

I'm home studying and I have no teacher.

My literature quotes a different calculator!!!

How can I use this calculator for reverse correlation coefficient. I can do it the other way round when I have all the X and Y values.

(Mode and choose stat, then choose 2, then input data then press AC, then shift 1 for stat then press 5 for reg and you get r)

But now I have been given the values of n, x, x^2, y, y^2, and xy and again need to get r!!

Any help greatly appreciated!!
