The regression equation is there to tell you the direction of the correlation. If you know r2 = 0.64 r 2 = 0.64, then r = ±0.8 r = ± 0.8. To decide on whether the correlation is positive or negative you should look at the slope of the regression line. Since the slope is negative, r = −0.8 r = − 0.8.This video shows how to find correlations coefficient for two variable statistics in a TI-84 graphing calculator.
