As x increases, does the value of r imply that y should tend to increase, decrease, or remain the same? Explain.

Since r is zero, as x increases, y decreases.

Since r is negative, as x increases, y remains the same.

Since r is negative, as x increases, y decreases.

Since r is positive, as x increases, y increases.

Since r is positive, as x increases, y remains the same.

I think it is D
