How do current - Potential Difference graphs show resistance.
Could you explain by the gradient.
Eg the higher the gradient of the graph - higher/lower resistance
The lower the gradient of the graph - higher/lower resistance

Depends on how you organize the graph. And how you define gradient.
R = E/I or in this case, R = ΔE / ΔI
So if the ΔE is large or ΔI is small, R is large.
or if ΔE is small or ΔI is large, R is small.
