Introduction to Cartesian Coordinate System - II
Any object, shape etc., is made up of Points, hence a proper understanding of points becomes necessary.
To Understand Points, it's important to know how to locate them.
There is a special system that we use in the world of Math to locate the points.
We call this system the Cartesian Coordinate System.
A point is represent in the form of (x,y)
The x-coordinate tells us where a point is in the "x direction" i.e the horizontal direction which is called the "x-axis".
Whereas the y-coordinate tells us where the point lies in the "y-direction" i.e the vertical direction which is called the "y-axis".
These two lines form a 2 Dimensional plane that we use to locate our points, which we call the Cartesian plane.
And the point at which these two lines meet is referred to as Origin, which is taken as the reference point.
We use Origin as a start point to locate any point in the cartesian plane.
Taking origin as the reference point, and a positive distance from it, we can represent the positive points.
But In the world of Maths, we have negative points too.
Hence, this led to the formation of negative x-axis and the negative y-axis.
The right side of origin on the x-axis represents the positive x, whereas the left direction represents the negative x.
The upward side of origin on the y-axis represents the positive y, whereas the downward side represents the negative y.
Let us have a quick revision.

The x-coordinate tells us where a point is in the "x direction" i.e the horizontal direction which is called the "x-axis".
The x-axis and y-axis with the origin form the Coordinate System.
The right side of origin on the x-axis represents the positive x, whereas the left direction represents the negative x.
The upward side of origin on the y-axis represents the positive y, whereas the downward side represents the negative y.
