None of these statements are true. The slope of the regression line can be negative if there is a negative correlation between the variables. The slope can also be greater than +1.00 if the units of measurement for the x and y variables are different. Finally, the slope can be equal to the correlation value if the standard deviations for both variables are equal to 1.
