Let us study about Coordinate plane,
The math term plane is a two dimensional flat surfaced with no thickness spanned with two linearly independent vectors and its extends its boundary forever. The generalization of the math term plane with higher dimension is called a hyper plane and the angle between the two intersecting plane is called dihedral angle.
In the term plane, there is only two axis are there,
* X axis (width);
* Y axis(Length)
I hope the above explanation was useful.
