This relationship, Ohm's Law, is obviously a linear relationship and thus the slope of the associated VI curve is just the constant of proportionality R. d V d I = V I = R. However, for a non-linear circuit element, e.g., V = R ⋅ ( I + ϵ I 3), the voltage across is not proportional to the current through and thus.
