Coordinate geometry is the
branch of mathematics where we
study the position of an object
on a plane with reference to two
mutually perpendicular lines in
the same plane.

The position of a point is located on a
plane by drawing two lines mutually
perpendicular to each other.
The plane is called the cartesian or
coordinate plane and the mutually
perpendicular lines are called axes.
The horizontal line is called the x-axis
and the vertical line is called the y-axis.

The plane is called the cartesian or

The horizontal line is called the x-axis
and the vertical line is called the y-axis.
The 'x-coordinate' of a
point is called the
abscissa.
The 'y-coordinate' of a
point is called the
ordinate.
The abscissa of every
point is 0 on the y-axis
and the ordinate of every
point is 0 on the x-axis.
The coordinates of the
origin are (0, 0).
