Coordinate Plane
Definition of Coordinate Plane
Coordinate Plane is a plane formed by the intersection of a horizontal number line with a vertical number line.
The horizontal number line is called the xaxis and the vertical number line is called the yaxis.
The number lines intersect at their zero points. This point of intersection is called the origin and written as (0, 0).

Solved Example on Coordinate Plane
Ques: Name the point having the coordinates ( 2.5, 2.5) on the coordinate plane.
Choices:
A. BB. E
C. G
D. C
Correct Answer: A
Solution:

Step 1: The ordered pair ( 2.5, 2.5) is 2.5 units to the left of the origin and 2.5 units up the xaxis.
Step 2: So, the point with the coordinates ( 2.5, 2.5) is B.
