Finding the Equation of a Regression Line In Exercises 1726, find the equation of the regression line for the data. Then construct a scatter plot of the data and draw the regression line. (Each pair of variables has a significant correlation.) Then use the regression equation to predict the value of y for each of the x-values, if meaningful. If the x-value is not meaningful to predict the value of y, explain why not. If convenient, use technology.Wins and Earned Run Averages The numbers of wins and the earned runaverages (mean number of earned runs allowed per nine innings pitched) foreight professional baseball pitchers in the 2012 regular season (Source: MajorLeague Baseball)Wins, x 20 18 17 16 14 12 11 9Earned run average, y 2.73 3.29 2.64 3.74 3.85 4.33 3.81 5.11(a) x = 5 wins (b) x = 10 wins(c) x = 21 wins (d) x = 15 wins
