Definition of Cartesian Coordinates
Cartesian Coordinate System consists of two axes, X and Y, which intersect each other at a point called `origin`, and is used to define the position of any point by using ordered pairs.
More About Cartesian Coordinates
 In twodimensional coordinate system, the reference of a point is given by using two coordinates, X and Y.
 In threedimensional coordinate system, the reference of a point is given by using three coordinates, X, Y, and Z.

Ques: Which of the given coordinates represents the point marked on the coordinate plane?
Choices:
A. (3, 4)B. (1, 1)
C. (2, 6)
D. (2, 5)
Correct Answer: D
Solution:

Step 1: The point is 2 units to the right of the Yaxis.
Step 2: So, the Xcoordinate is 2.
Step 3: The point is 5 units above the Xaxis.
Step 4: So, the Ycoordinate is 5.
Step 5: The coordinates of the point marked on the coordinate plane are (2, 5).
