Shannon drew the line of best fit on the scatter plot shown below: A graph is shown with scale along x axis from 0 to 10 at increments of 1 and scale along y axis from 0 to 15 at increments of 1.The ordered pairs 0, 14 and 1, 13.1 and 2, 12 and 3, 10 and 4, 8.5 and 5, 7 and 5.6, 6 and 6, 4.9 and 7, 3.4 and 8, 2.9 and 9, 2 and 9.5, 0.5 are shown on the graph. A straight line joins the ordered pairs 0,14 and 10, 0. What is the approximate equation of this line of best fit in slope-intercept form? A y = negative 7 over 5x + 14 B y = −14x + 7 over 5 C y = negative 5 over 7x + 14 D y = −14x + 5 over 7

y-intercept of line is 14 slope of line = (0 - 14)/(10 - 0) = -14/10 = -7/5 Required equation is y = -7/5 x + 14
