Question 332991: If the correlation coefficient is -0.79, what is the sign of the slope of the regression line? As the correlation coefficient increases from 0.21 to 0.28, do the points of the scatter plot move towar the regression line or away from it?

You can put this solution on YOUR website! I presume you are refering to simple regression
---
the correlation coefficient, r, and the slope of the regression line will always have the same sign

--
a higher correlation coefficient, r, mean that the data points are closer to being related linearly. So this means the points move toward the regression line.
