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?
y = 3x + 6 over 5
y = 5 over 6x + 3
y = 3x + 5 over 6
y = 6 over 5x + 3
