Plotting points are the process of locating a point whose co-ordinates are given. Those plotting points are done on the graph paper. This note has information about plotting in graph paper.
A branch of geometry which is used to identify a point on a plane is called Co-ordinate Geometry. The two mutually perpendicular number lines which are used to find the position of a point on a plane is called Rectangular axis.
Section formulae refer to the external and internal division of a line segment by a given point.
