Cartesian Plane and Quadrants
The Cartesian plane is a flat plane formed by two perpendicular number lines, the x-axis and y-axis, meeting at the origin and dividing the plane into four quadrants.
Practice This ConceptMain explanation
Teacher explanation
The horizontal line is the x-axis and the vertical line is the y-axis. Their meeting point is the origin (0, 0). The four regions are called quadrants. The signs of x and y decide the quadrant: I (+,+), II (-,+), III (-,-), and IV (+,-).
Example
The point (-3, 4) lies in Quadrant II because x is negative and y is positive.
Simple analogy
Start top-right as I, then move anticlockwise: I, II, III, IV.
Common confusion
Students sometimes decide the quadrant by the bigger number instead of using the signs of x and y.
Exam tip
For quadrant questions, check signs first and values later. The sign pattern is the fastest clue.
