A graph of electric current along the y-axis and potential difference along the x-axis gives a straight line passing through the origin. What does the slope determine?

While stud dying the dependence of potential difference (V) across a resistor on the current (I) passing through it, in order to determine the resistance of the resistor, a student took 5 readings for different values of current and plotted a graph between V and I. He got a straight line graph passing through the origin. What does the straight line signify? Write the method of determining resistance of the resistor using this graph.
