# Question: A scatter diagram includes the data points x 2

A scatter diagram includes the data points (x = 2, y = 10), (x = 3, y = 12), (x = 4, y = 20), and (x = 5, y = 16). Two regression lines are proposed: (1) ŷ = 10 + x, and (2) ŷ = 8 + 2x. Using the least-squares criterion, which of these regression lines is the better fit to the data? Why?
