Show supporting work for each section 

find regression equation 

choose correct graph 

a) predict the ERA for wins if it meaningful y=

b) predict the ERA for 10 wins if it meaningful y=

Find the equation of the regression line. Then construct a scatter plot of the data and draw the regression line. Then use the regression equation to predict the value of y for each of the given x-values, if meaningful. If the x-value is not meaningful to predict the value of y, explain why not.
