The calculator screen shows the linear regression for the data in the table. What type of correlation does the correlation coefficient indicate?

The screen shows, LinReg as a heading. Below that there is equation y = ax + b below this equation there is value of a that is a = -1.96341463. After that value of b is displayed, b = 19.09756098. Below the value of b, value of r square that is r square = .9817073171. After that value of r is displayed r = -.9908114438.
