a) predict the value of y for x=2 b) predict the value of y for x=2.5c) predict the value of y for x=14d) predict the value of y for x=3.5

Find the equation of the regression line for the given data. Then construct a scatter plot of the data and draw the regression line. (The pair of variables have a significant correlation.) Then use the regression equation to predict the value of y for each of the given x-values, if meaningful.
