## Quadrants of the Cartesian Coordinate System

The Cartesian Coordinate System can be broken up into several pieces: the x-axis, the y-axis, the origin (which lies on both axes), and the four

The x-axis, the y-axis, and the four quadrants are shown in the image below. The origin of the coordinate system is located at the intersection of the two axes.

**quadrants**. Each point on a flat surface must lie somewhere on either of the axes (or on both, in the case of the origin)**or**in one of the four quadrants.The x-axis, the y-axis, and the four quadrants are shown in the image below. The origin of the coordinate system is located at the intersection of the two axes.

Because

All points located on the

**Quadrant 1**is located to the right of the y-axis and above the x-axis, all of the points in Quadrant 1 have a positive x-coordinate and a positive y-coordinate.**Quadrant 2**is located to the left of the y-axis and above the x-axis. As a result, all of the points in Quadrant 2 have a negative x-coordinate and a positive y-coordinate.Because

**Quadrant 3**is located to the left of the y-axis and below the x-axis, all of the points in Quadrant 3 have a negative x-coordinate and a negative y-coordinate.**Quadrant 4**is located to the right of the y-axis and below the x-axis. As a result, all of the points in Quadrant 4 have a positive x-coordinate and a negative y-coordinate.All points located on the

**x-axis**have a y-coordinate equal to zero (including the origin), and all points located on the**y-axis**have an x-coordinate equal to zero (including the origin).
