Answer:
Cartesian coordinate system is used to specify any point on a plane.
In two dimensional plane,the two types of axes or coordinates are and
axis.
Explanation:
Cartesian coordinate system specifies each point and every point on axes.
A Cartesian Coordinate system in two dimension also named as rectangular coordinate system.
The two types of axes or coordinates are and
axis.
The horizontal axis is -axis and vertical axis is named as
-axis.
The coordinate system specifies each point as a set of numerical coordinates in a plane which are signed from negative to positive. that is from (,
).
In three dimensional plane, ,
and
coordinates are used and in two dimensional plane,
and
coordinates are used to address any point in the interval (
,
).
For defining both the coordinates, the two perpendicular directed lines - axis and
-axis are drawn.
Now, for example is a point in which indicates that the value of
is
and
is
.
It is drawn by moving units right from the origin to positive
axis and
units upwards from the origin
to positive
-axis.
