Two variables have a positive linear correlation. Is the slope of the regression line for the variables positive or negative?

Two variables have a positive linear correlation.
Is the slope of the regression line for the variables positive or negative?
A. The slope is negative. As the independent variable increases the dependent variable also tends to increase.
B. The slope is negative. As the independent variable increases the dependent variable tends to decrease.
C. The slope is positive. As the independent variable increases the dependent variable tends to decrease.
D. The slope is positive. As the independent variable increases the dependent variable also tends to increase.

The correct answer is D. The slope is positive. As the independent variable increases the dependent variable also tends to increase.
