What We Have Discussed

We need references to locate the exact position of a point in a plane.

A point or an object in a plane can be located with the help of two number lines. One of them is line (X-axis) and the other is line (Y-axis).

The representing of points in the plane in the form of coordinates ‘x’ and ‘y’ are called Coordinates.

The point of intersection of X-axis and Y-axis is the .

The ordered pair (x, y) is from the ordered pair (y, x).

The equation of X-axis is = 0.

The equation of Y-axis is = 0.
