Axis
In a coordinate system, the axes are the reference lines (named the x- and y-axis) that form the coordinate plane. The intersection of a horizontal number line, called the x-axis, and a vertical number line, called the y-axis.
Origin:
In the 2D coordinate plane, the origin is the intersection of the x-axis and the y-axis.

Quadrant:
In mathematics, a quadrant is one of the four sections of a rectangular coordinate plane.
Signs of the coordinates in a quadrant
The signs of coordinates of any point plotted in a particular quadrant are the same. A point cannot lie on both a quadrant and an axis. Points that lie on either axis have one coordinate that is 0, which is neither positive nor negative. The diagram below shows the signs of coordinates in different quadrants.
