The process to determine resistance per cm of a given wire by plotting a graph of potential difference versus current is given below.

If you plot the potential difference along the X-axis and the current along the Y-axis, the reciprocal of the slope gives the material's resistance, R.
If you interchange the quantities on the axes, the resistance will be given by its slope and not it's reciprocal.
The resistance per cm is given by R/l if the length of the resistance wire is 'l' cm.
