Location - Plot Points on a Cartesian Plane . The Cartesian Plane is a co-ordinate system for locating and labelling unique points on a plane (flat/2D) surface. Co-ordinates indicate the distance from the origin, which is the starting point of each axis, in each direction. . Invention of this system for locating a point in 2D space is attributed to Rene Descartes (also known as Cartesius), a French philosopher, scientist and mathematician who lived in the 17thCentury AD. There is a legend that D

The Cartesian coordinate system is a method for describing points using two perpendicular axes: the horizontal x-axis and the vertical y-axis, which meet at a point called the origin. Every point in the plane is represented by an ordered pair (x, y), where x tells you how far to move left or right from the origin, and y tells you how far to move up or down. This system is especially useful for problems involving straight lines, rectangular shapes, and algebraic equations. It can also be extended
