RESISTIVITY (help)

[JoneS]

it all seemed pretty easy to start off with i've got all my results.
Voltage against current with a variable thing. but i can't do the equation, i have drawen up the graphs and followed the formulas but the results all come out wrong.

formulas: m=y/x m=volt/amp r=1/m which is the resistance
resistivity= r=p*a/l p=r*l/a

After competing these formulas the result comes out wrong HELP[:(] [*(]
