To get from point E (1,3) to E' (3-1) you add 2 units to the x coordinate since the x-axis goes from left to right  and moving to the right means its positive and then you subtract 4 from the y coordinate since the y axis is going up and down and when you move -4 points you move down 4 points. You do this to every other point get the new figure.
