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 x-axis and the vertical number line is called the y-axis.
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.
Correct Answer: A
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 x-axis.
Step 2: So, the point with the coordinates (- 2.5, 2.5) is B.
