Hi, 

- If the correlation coefficient is 0.97, what is the sign of the slope of the regression line? 

- As the correlation coefficient increases from -0.78 to -0.74, 

do the points of the scatter plot move toward the regression line, or  from it?

 Note: |-.74| < |-.78|, the lesser the correlation, the more the scatter
