Coordinate Geometry is a branch of mathematics that uses a coordinate system to describe the positions of points, lines, and shapes in a two-dimensional or three-dimensional space. It combines algebra and geometry, allowing us to represent geometric figures using numerical coordinates. For example, in a Cartesian coordinate system, each point is defined by an ordered pair of numbers (x, y) that indicate its position on a grid. This field helps in solving geometric problems by translating them into algebraic equations. For instance, the equation of a line can be expressed in the form y = mx + b, where m is the slope and b is the y-intercept. Coordinate Geometry is widely used in various applications, including computer graphics, engineering, and navigation.
