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 x-axis and the vertical number line is called the y-axis.

              

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 x-axis.

Step 2: So, the point with the coordinates (- 2.5, 2.5) is B.
