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	775	619	519	508	491	474		(a) x=503 feet	(b) x=644 feet
Stories, y	53	47	46	41	38	37		(c) x=310 feet	(d) x=733 feet
