Quadrants:

The

$x$ -axes and

$y$ -axes divided the cartesian plane into four infinite regions with equal distance from the origin and bordered by two axes.

These are called quadrants. Quadrants divide the cartesian plane into

$4$ equal parts. They are usually numbered in anticlockwise direction starting from the region bounded by positive

$x$ and

$y$ -axis (that is

$OX$ ).

Quadrant I:

Any point located in quadrant $I$ will have a positive number in the $x$ - and $y$ -axis.
It can be represented as $( x, y)$ , where $x$ and $y$ represent the distance of a point from the origin horizontally and vertically.

Example:

$(2,3)$ ,

$(6,10)$ ,

$(9,12)$

Quadrant II:

Any point located in quadrant $II$ will have a negative number in the $x$ - and positive number in $y$ -axis.
It can be represented as $(-x, y)$ , where $x$ and $y$ represent the distance of the point from the origin horizontally and vertically.

Example:

$(-3,6)$ ,

$(-2,5)$ ,

$(-15,12)$

Quadrant III:

Any point located in quadrant $III$ will have a negative number in the $x$ - and $y$ -axis.
It can be represented as $( -x, -y)$ , where $x$ and $y$ represent the distance of the point from the origin horizontally and vertically.

Example:

$(-5,-6)$ ,

$(-2,-1)$ ,

$(-8,-10)$

Quadrant IV:

Any point located in $IV$ will have a positive number in the $x$ - and negative number in $y$ -axis.
It can be represented as $(x, -y)$ , where $x$ and $y$ represent the distance of the point from the origin horizontally and vertically.

Example:

$(1,-3)$ ,

$(3, -4)$ ,

$(7,-1)$
