Coordinate Planes


Coordinate Plane:

In this Blog before we get into the details of coordinate planes,let us first understand the definition of a coordinate plane.The basic meaning of a coordinate plane is Coordinate plane is a plane formed by the intersection of a horizontal number line.






















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.

This is a coordinate plane. It has two axes and four quadrants. The two number lines form the axes. The horizontal number line is called the x-axis and the vertical number line is called the y-axis. The center of the coordinate plane is called the origin. It has the coordinates of (0,0). Locations of points on the plane can be plotted when one coordinate from each of the axes are used. This set of x and y values are called ordered pairs.




















With the help of another example we can get a clear understanding about the coordinate Planes.



In the coordinate plane there are four quadrants.

Quadrant 1.

In quadrant 1 both X axis and Y axis values are positive. [( +x, +y )]

Quadrant 2

In quadrant 2 X axis values are negative and Y axis values are positive. [( - x, +y )]

Quadrant 3

In quadrant 3 X axis values are positive and Y axis values are negative. [( + x, - y )]

Quadrant 4

In quadrant 4 both X axis and Y axis values are negative. [( - x, - y )]
