We are familiar with the representation of real numbers on a line,
which we call a real line. In this representation we fix a point O
(called origin) and represent a real number by a point A on this line
such that its distance OA is equal to the value of real number. In the
left side of O we represent negative real numbers and in the right
side of O we represent positive real numbers. Thus, not only the
magnitude of OA but the direction of the line OA is also considered
for representation. Read more - http://smartlearnwebtv.com/iitjee/IITJEE/representation-of-points-in-a-plane/
