Answer:
since the potential difference and current has a direct relationship, potential difference is directly proportional to current in the current ( ohm's law),thus the shape of the graph between them is a straight line.
moreover,the slope of the graph will be the resistance of the conductor because it is the proportionality constant.
and the equation ,v= ir
is similar to y= mx+ c
where m is the slope.
