Coordinate means the pair of points which is located on the two dimensional plane. It contains the horizontal line called the x-axis and the vertical line called y-axis.

The point of intersection of the x and y-axis is called the origin whose coordinate is (0, 0).

X and Y axis are two real number lines which have the common origin 0. The real numbers to the right of 0 (on the x-axis) are positive and those which are on the left 0 (on the x-axis) are negative.

Similarly, the numbers which are above 0 (on the y-axis) are positive and those which are below 0 (on the y-axis) are negative.The following figure shows the positive and negative real numbers on the x and y axis of the co-ordinate plane:

### Coordinates of Points on the x- and y-axis:

**On the x-axis, y-coordinate is zero.**Hence, the coordinate form of the points on the x-axis is (x, 0).

**On the y-axis, the x-coordinate is zero.**Hence, the coordinate form of the points on the y-axis is (0, y).

The following figure shows the points on the x and y axis:

### Location of Coordinates of the Form (x, y) on the Graph, where x $\neq$ 0 and y $\neq$ 0:

While locating the required points which are unique on the coordinate plane, we look for the corresponding real number on the x and y axis respectively. The intersection of the vertical line from the x-axis and the horizontal line from the y-axis is the required point in the coordinate plane.

The following figure shows the location of the points (3, 5), (-3, 5), (-4, -5) and (6, -4) which are in different quadrants.
