Asked by Tommy
If the slope of the regression line is negative and the correlation coefficient is -0.5, coefficient of determination is:
r = -0.5 r2 = 0.25 but because slope of regression line is negative, then coefficient of determination would be also negative. r2 = -0.25
r = -0.5 r2 = 0.25 but because slope of regression line is negative, then coefficient of determination would be also negative. r2 = -0.25

The coefficient of determination is always positive.
