Since the graph is a representation of an equation, you can check to see whether a point is on a graph by seeing if the given point satisfies the equation. By this I mean, take the "x" value and "y" value of the point and replace the x and y variables in the equation with these values. If you get equality, then the point is on the graph.
I hope that this explanation helps.
