To locate a point in the plane We require two perpendicular axes one of them is horizontal and other is Vertical.The plane is called Cartesian plane and axis are called the coordinates axis
The horizontal axis is called x-axis and Vertical axis is called Y-axis.
Quadrants:-The axes divide the Cartesian plane in to four parts. These Four parts are called the quadrants
Origin:- The point of intersection of axis is called origin.
Abscissa:- The distance of a point from y axis is called x –coordinate or abscissa.
Ordinate:- the distance of the point from x –axis is called y – coordinate or Ordinate.
The coordinate of the origin is (0,0).
A point on the x –axis has zero distance from x-axis so coordinate of any
Point on the x-axis will be (x, 0).
A point on the y –axis has zero distance from y-axis so coordinate of any
