Locating Objects or Points in a Cartesian Plane
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.
