Identify the equation of the least squares regression line that most
closely matches the data set.

yˆ = 0.17x − 13.2
yˆ = 5.5x + 52
yˆ = 3.5x − 6921.2
yˆ = −2.2x + 13.8

To select the correct response, you'll have to find the slope, m, and the y-intercept, b, of the regression line based upon the given five points.

Where might you be able to find the equations for deriving slope and y-intercept for a regression line when starting with a set of points?
