The x- and y- axes divide the coordinate plane into four regions. These regions are called the quadrants.

Examples of Quadrants

The figure below shows the four quadrants of the coordinate plane.

Solved Example on Quadrants

Ques: Identify the quadrants in which the points (- 4, 2) and (3, - 8) are located.

Choices:

A. first and second quadrants respectively
B. second and third quadrants respectively
C. second and fourth quadrants respectively
D. only the second quadrant
Correct Answer: C

Solution:

Step 1: Start at the origin.
Step 2: Move 4 units to the left from the y-axis.
Step 3: Then move 2 units above the x-axis.
Step 4: The point (- 4, 2) is in the second quadrant.
Step 5: Move 3 units to the right from the origin on the x-axis.
Step 6: Then move 8 units below the x-axis.
Step 7: The point (3, - 8) is in the fourth quadrant.
Step 8: The points (- 4, 2) and (3, - 8) are in the second and fourth quadrants respectively.
