Question:

The square footages and sale prices (in thousands of dollars) of seven homes in Akron, Ohio, are shown in the table at the left. 

(a) x = 1450 square feet 

(b) x = 2720 square feet

(c) x = 2175 square feet 

(d) x = 890 square feet

Square footage, x Sale price, y 1490 145.0 1122 84.9 1112 119.9 720 44.9 2509 289.0 2448 229.0 189.9 1786


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.
