Answer:
See included figure.
Explanation:
I assume you are given a grid to plot on, but I've just quickly made one myself to show how to do it.
First off: remember that in a point with two coordinates it's always (x,y).
This means the first number is the x coordinate and the second number is the y coordinate.
So all you have to do then is make some lines through those coordinates, then the point is the point where those two lines intersect.
