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!"

## Glossary

### coordinate

One of the measurements of distance of a point from the axes of the graph.

### graph

A diagram showing a relationship between two variables.

The diagram shows a vertical y axis and a horizontal x axis.

The diagram shows a vertical y axis and a horizontal x axis.

### origin

The point from where all measurements of coordinates are made; usually the point where the two axes of a graph cross.

### union

The union of two sets A and B is the set containing all the elements of A and B.
