Graph each scatter plot. Find r, the equation of the regression line, and make a prediction for the of x that is given. For Exercises 12 through 27, use the same data as for the corresponding exercises in Section 10-1. For each exercise, find the equation of the regression line and find the y' value for the specified x value. Remember that no regression should be done when r is not significant. 12.
