Coordinate geometry is an essential branch of mathematics that combines algebra and geometry. It provides a framework for representing and analyzing geometric figures using coordinates on a plane. The Cartesian coordinate system, developed by René Descartes, is the foundation of coordinate geometry.

The system consists of two perpendicular number lines, the x-axis and the y-axis, intersecting at a common point called the origin. Each point on the coordinate plane can be uniquely identified by an ordered pair of numbers (x, y), where x represents the horizontal position along the x-axis, and y represents the vertical position along the y-axis.

For example, the point (2, 3) denotes a position that is 2 units to the right and 3 units upwards from the origin. By assigning coordinates to points, we can describe and study various geometric shapes, such as lines, circles, and polygons, using algebraic equations and formulas.
