Finding the location (address) of an object or a point in a Cartesian plane by using the coordinates (

*x*-coordinate and*y*-coordinate) of the object or point.### Properties

- The coordinates are
**numbers**. - The two axes are
**perpendicular**. - The subdivisions on the axes are the
**same length**. - The frame of reference of the axes (origin, scale, etc.) are identical.

### Examples

- The coordinates of the cat are (3, 4). The
*x*-coordinate is 3 and the*y*-coordinate is 4. - The coordinates of the dog are (–3, 4). The
*x*-coordinate is –3 and the*y*-coordinate is 4. - The coordinates of the bird are (3,–4). The
*x*-coordinate is 3 and the*y*-coordinate is –4. - The coordinates of the rabbit are (–3,–4). The
*x*-coordinate is –3 and the*y*-coordinate is –4.
