We also know that the resistance of 2 salt bridges is half that of 1 salt bridge, so the resistance of "n" salt bridges is R B x 1/n. We thus end up with an equation: V V = -V B x 1/n + V T. This is in the form y = mx + c, so if you plot V V on the y-axis against 1/n on the x-axis, the slope should be V T.
