Ben drew the line of best fit on the scatter plot shown.
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, 2 and 1, 2 and 2, 4 and 3, 3 and 4, 6 and 5, 6 and 6, 7 and 7, 8 and 8, 11 and 9, 13 and 10, 15 are shown on the graph. A straight line joins the ordered pairs 0, 1 and 10, 15.
What is the approximate equation of this line of best fit in slope-intercept form? (5 points)
