  1. Cartesian coordinate system - Wikipedia

    Illustration of a Cartesian coordinate plane. Four points are marked and labeled with their coordinates: (2, 3) in green, (−3, 1) in red, (−1.5, −2.5) in blue, and the origin (0, 0) in purple.

  2. Cartesian Plane - Definition, Meaning, Quadrants, Examples

    Cartesian Plane is a two-dimensional plane that is part of the cartesian coordinate system. The cartesian plane was invented by Rene Descartes in the 17th Century. The most important …

  3. Cartesian coordinates | Definition & Facts | Britannica

    Dec 11, 2025 · The Cartesian plane is a two-dimensional space with a horizontal axis, typically labeled x, and a vertical axis, typically labeled y. Both axes are lines extending infinitely in …

  4. Cartesian Coordinates - Math is Fun

    Using Cartesian Coordinates we mark a point on a graph by how far along and how far up it is: The point (12,5) is 12 units along, and 5 units up. They are also called Rectangular …

  5. Section 3.1: Cartesian Plane - Mathematics LibreTexts

    The rectangular coordinate system is also called the xy -plane, the coordinate plane, or the Cartesian Plane. The horizontal number line is called the x-axis, and the vertical number line is …

  6. What is the Cartesian plane, and how do I use it? | Purplemath

    What is the Cartesian plane? The Cartesian ("karr-TEE-zhun") plane — named for its originator, René Descartes — is a way to precisely name points in the geometric plane.

  7. Coordinate Plane or Cartesian Plane (solutions, examples, videos)

    The coordinate plane or Cartesian plane is a basic concept for coordinate geometry. It describes a two-dimensional plane in terms of two perpendicular lines or axes: x -axis and y -axis.

  8. Introduction to Coordinate Geometry and the Cartesian Plane

    In coordinate geometry, points are placed on the "coordinate plane" as shown below. It has two scales - one running across the plane called the "x axis " and another a right angles to it called …

  9. Cartesian Plane: Definition, Quadrants & How to Plot Points

    A Cartesian plane, also known as a coordinate plane or x-y plane, is a two-dimensional surface formed by two perpendicular number lines called the x-axis (horizontal) and the y-axis (vertical).

  10. What is the Cartesian Plane? - Interactive Mathematics

    What is the Cartesian Plane? In geometry, the cartesian plane is a two-dimensional surface that contains two perpendicular axes, the x-axis and the y-axis. The cartesian plane is also known …
