What is a cartesian/coordinate plane?
Cartesian Coordinates : These are named after the French mathematician Descartes who used these for studying “analytical geometry”. This gives a method of defining the position of a point by its distance from a fixed point (origin) in the direction of two or more straight lines. In a plane two straight lines called the x-axis and y-axis form the basis of a two dimensional coordinate system. The point of intersection of the two axes is called the origin. An imaginary grid is formed by lines parallel to the axes and unit distance apart. For example, the point (3,5) is the point where the line parallel to y-axis three units away from y-axis, meets the line parallel to x-axis five units away from x-axis. The position of a point in space can be determined by three measurements with respect to three concurrent lines called axes of coordinates. These axes form a frame of refence and the point of concurrency is the origin of coordinates. The axes are referred to as x-axis, y-axis, and z-axis,
