The Coordinate Plane

Concept

Quadrants

In a coordinate plane, the intersection of the x-axis and the y-axis produces four regions called quadrants. The quadrants are numbered counterclockwise from the top right quadrant as Quadrant I to Quadrant IV in the bottom right.

The signs of the coordinates of a point can be determined based on which quadrant the point lies in.

Conversely, the quadrant of a point can be found by looking at the signs of its coordinates.

Points on an axis do not belong to any quadrant.
