You use the y=mx+b formula where the 5/11 is the slope or rise/ run and the 5 is the y intercept; so you put your first point at 5 on the y axis, then from there you take the 5/11 to mean you go up 5 spaces from the y intercept and then go over to the right 11 spaces and to draw the line in the other direction you go down 5 spaces from the 5 or y intercept and then to the left 11 spaces because going down and to the left on a graph means both number in the slope are negative, and two negatives equals a positive
