Coordinate system
A coordinate system is a way to define the position of points, lines, or shapes in a space using numbers. In a 2D plane, like on a graph, each point is identified by two numbers: an x-coordinate (horizontal position) and a y-coordinate (vertical position). In 3D space, a third number (z-coordinate) specifies depth. This system allows us to easily describe locations and navigate spaces, making it fundamental in fields like geography, engineering, and computer graphics. Different types of coordinate systems, such as Cartesian or polar, serve various purposes depending on the context.

A coordinate system is a method used to locate points in space using numbers. Imagine a grid with two lines that cross at right angles, like a plus sign. The vertical line is called the y-axis, and the horizontal line is the x-axis. Each point is identified by a pair of numbers (x, y), indicating its position along these axes. In three dimensions, we add a z-axis for depth. This system helps us navigate maps, graph equations, and understand spatial relationships in various fields, from geography to science and engineering.
