Compute r. (Round your answer to four decimal places.)
As x increases, does the value of r imply that y should tend to increase or decrease? Explain your answer.
Given our value of r, y should tend to remain constant as x increases.
Given our value of r, y should tend to decrease as x increases.
Given our value of r, y should tend to increase as x increases.
Given our value of r, we can not draw any conclusions for the behavior of y as x increases.
