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 xvalues, if meaningful. The table below shows the heights (in feet) and the number of stories of six notable buildings in a city.
