Start at the origin (where the the x and y axis intersect)
Now move your pencil 4 units to the left
We move 4 units in this direction since the x-coordinate is -4 (its the first number of the pair)

Now go 3 units up
We move 3 units in this direction since the y-coordinate is 3 (its the second number of the pair)

Plot a point where the pencil lands

So here is the point (-4,3)
