A line in the xy-plane that passes through the points ^x1 y1 h and ^x2 , y2 h has a slope of y x 2 2 - - y x1 1 .

It follows that the slope 4.4-3.2 1.2 0.6 of the line of best fit is approximately 2-0 , which is equivalent to 2 , or . 0.6 Therefore, of the given choices, is closest to the slope of the line of best fit shown.
