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.

Negative r = inverse relationship, while positive r = direct relationship. Does that help?
