Find the equation of the regression line for the given data. The 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. 772. 628. 518. 508. 496. 483

Stories, y. 51. 48. 46. 41. 38. 37

a) x=498 feet. b) =639 feet

c) x=315 feet. d) x=730 feet

1. Find the regression equation.

2. Determine the order pairs to be plotted.

3. Predict the value of y for each of the given x-values in the range of the original data it is meaningful to predict the value of y for x.
