Coordinates (x,y) give the position of a point on a graph. The x coordinate tells you how far across and the y coordinate tells you how far up.

The coordinates (2,3) indicate a point 2 units to the right of the origin and 3 units up.

The coordinates (-4,-1) indicate a point 4 units to the left of the origin and 1 unit down.

Some people remember this as "along the corridor and up the stairs" or "x is a cross, wise up!"
