Step-by-step explanation:
A relative point can be discussed in Chemistry, physics or mathematics.
Generally, a relative point is the point in relation to a given point in coordinates system in the same plane, whose coordinates can be used to identify the coordinates of the other point. Also in speed and motion a relative point is the point in relation to which the parameters of other objects can be found.
For Example: A moving car speed in relation with the boy walking on the road.
