Rearrange R=V/I so that it is in the form Y=MX+C

R = V/I

R is resistance

V is voltage

I is current

We can multiply by I both side

I*R = (V/I) * I

I will cancel out from right side

so IR = V

we can write it

V = IR

V = RI + 0

This equation is same as Y = MX + C

here Y is V

M is R which shows slope in a graph and it is constant

C is Y intercept but it will be zero because if potential difference is zero then current will also be zero

R = (1/I) V

V = (I) R

V = (R) I

I = (1/R) V

There are no "y-intercepts".

C=0 in all forms.
