# Cartesian Coordinate System

Cartesian coordinate system is a two/three dimensional plane with two/three axes. In two dimensional plane there are two axes, a horizontal axis, known as the x-axis and a vertical axis, known as the y-axis used to plot points and line graphs. It was invented by the French Mathematician Rene Descartes. Each point is represented by an ordered pair (x, y). The two axis splits the coordinate system into four quadrants.

Any Point in the first quadrant will be positive for both x and y.

In second quadrant the points will have negative x and positive y.

Any Point in the third quadrant will be negative for both x and y.

The fourth quadrant contains points with positive x and negative y coordinates.
