Answer:
The Cartesian coordinate plane, also known as the Cartesian plane or Cartesian coordinate system, is a two-dimensional coordinate system that specifies each point uniquely in a plane by a set of numerical coordinates. It was developed by the French mathematician and philosopher René Descartes.
The Cartesian plane is formed by two perpendicular lines intersecting at a point called the origin. The horizontal line is called the x-axis, and the vertical line is called the y-axis. The point where the axes intersect is assigned the coordinates (0,0).
The coordinates of a point on the plane are represented as (x, y), where x is the horizontal distance (along the x-axis) and y is the vertical distance (along the y-axis). The x-coordinate indicates how far to the right or left the point is from the origin, and the y-coordinate indicates how far up or down the point is from the origin.
The Cartesian coordinate system is widely used in mathematics, physics, engineering, computer science, and various other fields to represent and analyze geometric shapes, equations, and relationships between variables. It provides a systematic way to describe the position of points in a plane using numerical values.
