Definition

1. Noun:
   • A coordinate plane: A two-dimensional plane formed by two perpendicular number lines that intersect at a point called the origin. Every point on this plane can be uniquely identified by an ordered pair of numbers, known as Cartesian coordinates.

Usage

• The Cartesian plane is the fundamental framework for graphing algebraic equations and geometric shapes.
• In mathematics, the Cartesian plane is used to visually represent relationships between two variables.

Examples

• Noun:
  • The student plotted the linear equation y = 2x + 1 on the Cartesian plane.
  • The concept of the Cartesian plane is essential for understanding coordinate geometry.

Advanced Usage

• "The Cartesian plane is divided into four quadrants.": This describes the four regions created by the intersection of the x-axis and y-axis, numbered counterclockwise from the upper right.
• "Mapping data onto a Cartesian plane": Refers to the process of representing numerical data as points on this coordinate system for analysis.

Variants and Related Words

• Coordinate plane (n): A synonym for Cartesian plane.
• Cartesian coordinates (n): The ordered pair (x, y) that defines the position of a point on a Cartesian plane.
• Cartesian coordinate system (n): The system comprising the Cartesian plane and its axes.

Synonyms

• Coordinate plane: A plane with a coordinate system.
• Coordinate grid: A network of lines on such a plane.

Related Terms

• X-axis (n): The horizontal number line on a Cartesian plane.
• Y-axis (n): The vertical number line on a Cartesian plane.
• Origin (n): The point (0, 0) where the x-axis and y-axis intersect.

Noun

1. a plane in which all points can be described in Cartesian coordinates
