Dennis 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, 15 and 0.5, 14 and 1, 13 and 2, 12 and 3, 11 and 4, 9 and 5, 8 and 6, 6 and 7, 4.5 and 8, 2.3 and 9, 2 and 9.8, 0.5 are shown on the graph. a straight line joins the ordered pairs 0, 15 and 10, 0. what is the approximate equation of this line of best fit in slope-intercept form
