# The Coordinate Plane

A coordinate plane is the rectangular plane formed with two number lines one is vertical number line and the other one is the horizontal number line. In the horizontal number line at left side negative Numbers are placed and at the right hand side the positive numbers are placed.
In case of vertical axis upper part contains positive numbers and lower part contains negative numbers. The horizontal line represents the x-axis and the vertical line represents the y-axis. There are four quadrants and two axis in a Coordinate Plane. The x-axis is also named as Abscissa and the other name of y-coordinate is Ordinate.
Suppose we have to locate a Point then we require a coordinate which is known as Ordered Pair and these are Set of ‘x’ values and ‘y’ values. The first coordinate in the ordered pair known as Domain which is usually the x-coordinate, and the second coordinate which is usually the y-coordinate is known as The Range. It must be noted that the value which a domain contains is usually the independent value and the value which range contains is the value corresponding to the dependent value. The coordinate plane is a two-dimensional surface on which lines, points and curves are plotted with the help of ordered pair. Origin is the point where 0 is placed and 0 is equidistant from both horizontal and vertical axis. Two axes divide the plane into four quadrants. As we know that coordinate plane is made with the help of convection, so convection are also helpful in defining the quadrants, the first quadrant is at the top right side of the plane and rest are counted in anti-clockwise format. This is all about coordinate planes.

## History of Coordinate Plane

Coordinate plane is a plane which has two axes and four quadrants. Horizontal number lines are along x – axis and vertical number lines are along y – axis. In Coordinate Plane center Point is known as origin. Its coordinate value is (0, 0). Now let's have a look on History of Coordinate Plane. Concept of Coordinate plane was given by French mathematician, phi...Read More

## Origin of Plane

The Point where the horizontal axis and vertical axis meet is called origin of plane. We can easily understand this with the help of Coordinate Plane. A coordinate plane consists of two axes (plural of axis) and four quadra...Read More
