Dan 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 and scale along y axis from 0 to 15 at increments of 1. the ordered pairs 0, 4 and 1, 4 and 2, 5 and 3, 6 and 4, 7 and 5, 9 and 6, 10 and 7, 11 and 8, 13 and 9, 14 and 10, 15 are shown on the graph. a straight line joins the ordered pairs 0, 3 and 10, 15. what is the equation of this line of best fit in slope-intercept form?
