The layout of each of the coordinates is (x,y) so for the first coordinate (7, 13) you start at zero and go right 7 then up 13. And draw a little cross there or something. If it’s a negative number like (-13, -9) go left 13 from 0 and then go down 9 and draw a little cross again. After you have completed each line you have to join them up (like dot to dot) in the order that you drew them.
