Coordinate Plane
A coordinate plane, also known as a Cartesian plane, is a two-dimensional plane formed by two number lines, called the x-axis and y-axis, that intersect at a right angle at their zero points. The x-axis is the horizontal line, and the y-axis is the vertical line. The point where the axes intersect is called the origin and is denoted as (0, 0).
Parts of the Coordinate Plane:
- Origin: The point of intersection of the x-axis and y-axis, denoted as (0, 0).
- X-axis: The horizontal line on the coordinate plane.
- Y-axis: The vertical line on the coordinate plane.
- Quadrants: The coordinate plane is divided into four quadrants labeled as I, II, III, and IV, moving counterclockwise from the top right quadrant.
Coordinates:
Coordinates are used to locate points on the coordinate plane. The x-coordinate represents the horizontal position of a point, and the y-coordinate represents the vertical position of a point. Coordinates are written in the form (x, y).
