SOLVED:Plot the points and determine whether the data have positive, negative, or no linear correlation (see figures below). Then use a graphing utility to find the value of r and confirm your result. The number r is called the correlation coefficient. It is a measure of how well the model fits the data. Correlation coefficients vary between -1 and 1, and the closer |r| is to 1, the better the model. (1,3),(2,6),(3,2),(4,3),(5,9),(6,1)
