The
horizontal line is called axis.
Vertical
line is called axis.
The
intersection of lines is called origin it is represented by .
Quadrants:
The
Cartesian plane is divided into parts by coordinate axes called quadrants.

Any
point in Cartesian plane is represented byordered
pair ![](https://tutormate.in/wp-content/uploads/2018/10/cartetian-plane3.png)
The
distance of P from axis It is called co-ordinate (Abcissa)
The
distance of P from axis It is called co-ordinate (ordinate)

If point
is in quadrant it has both coordinates positive.
If point
is in quadrant it has x coordinate negative and y
coordinate positive.
If point
is in quadrant it has both coordinates negative.
If point
is in quadrant it has x coordinatepositive and y
coordinate negative.

If point
is on axis,its coordinate is zero. It is of the form
If point
is on axis,its coordinate is zero. It is of the form Co ordinate of origin is
