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.
