Introduction

If we take two number lines, one horizontal and one vertical, and then combine them in such a way that they intersect each other at their zeroes, and then they form a Cartesian Plane.

  • The horizontal line is known as the x-axis and the vertical line is known as the y-axis.
  • The point where these two lines intersects each other is called the origin. It is represented as ‘O’.
  • OX and OY are the positive directions as the positive numbers lie in the right and upward direction.
  • Similarly, the left and the downward directions are the negative directions as all the negative numbers lie there.
