The process of discerning whether a point belongs to a graph requires a verification step where the coordinates of the point are substituted into the equation of the graph. If the equation remains valid post-substitution, the point can be said to be a part of the graph. This principle is applicable for all kinds of curves, be it lines, circles or parabolas.
