The graph is given below:

The current (I) is marked on the X axis and the potential difference (V) on the Y axis.

Explanation: According to Ohm's law, the electric current flowing through the metallic wire is directly proportional to the potential difference V across its ends when the temperature remains the same.

V I

V/I = constant

= R

Therefore, V = IR

R is the constant and is known as resistance.

This shows that greater the potential difference, greater is the flow of current. Similarly, lower the V, lower is the value of I.
