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. They intersect at their zero points. This point of intersection is called the origin and written as (0, 0).

On a coordinate plane, the horizontal number line is called the xaxis and the vertical number line is called the yaxis.
Solved Example on Coordinate Plane
Name the point having the coordinates ( 2.5, 2.5) on the coordinate plane.
Choices:
A. B
B. 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.
