In a simple regression analysis, the correlation between the two variables (xx and yy) is strong and negative. Does this imply that?

• An increase in xx causes yy to decrease and vice versa.
• The slope of the regression line will be negative.
• As xx decreases, yy tends to increase.
• As xx increases, yy tends to increase.
• An increase in xx causes yy to decrease.
• As xx decreases, yy tends to decrease.
• A decrease in xx causes yy to increase.
