- If the correlation coefficient is -0.53, what is the sign of the slope of the regression line?
Answer: Since the correlation coefficient is negative, the slope of the regression line is negative

- As the correlation coefficient increases from 0.51 to 0.56, do the points of the scatter plot move toward the regression line, or away from it?
Answer: as the correlation coefficient increases to 1, the points will move closer to the regression line. Remember that a larger correlation coefficient (in absolute value) means a stronger correlation.
