First you draw a straight horizontal line, then
you draw another line through the middle of the
first line. Both these lines are done on graph paper.
Now where the lines cross is (0, 0) the origin.
Start marking off equal segments right and left
along the horizontal line (x axis). You will require a -1 and -2
to the left and a 1, and 2 to the right.
Now start to mark off equal segments up and down the
vertical axis (y axis) You will need 7 segments marked 1 - 7 upwards
and 7 segments marked -1 - -7 downwards.
Now taking the fist coordinate (-2, 7) Move to the
left till you reach -2 and then move upwards till you reach
7 on the y axis. Make a mark. Next move across to left till
you reach -1 then move upwards till you reach 4 on the y axis.
You carry on this procedure for all the coordinates then you draw a line
through all the dots.

Hope this helps.
