In mathematics, the Cartesian coordinate system is used to determine each point in a plane through two numbers called the x-coordinate and the y-coordinate.
To define the coordinates, two perpendicular directed lines are specified, as well as the unit length, which is marked off on the two axes. The systems are also used in space and in higher dimensions. Using the Cartesian coordinate system, the geometric shapes can also be described by algebraic equations.
