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. The table below shows the heights (in feet) and the number of stories of six notable buildings in a city. Height, X 778 621 519 510 494 473 (a) x - 498 feet (b) x=647 feet Stories, y 51 47 44 42 39 38 (c) x - 798 feet (d) x - 729 feet Find the regression equation. y =x + (D (Round the slope to three decimal places as needed.
