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.
