4. Maximum surface resistance. Consider a square sheet of side L, thickness d, and
electrical resistivity p. The resistance measured between opposite edges of the sheet
is called the surface resistance: R = pL/ Ld = p/d, which is independent of the
area of the sheet. (R is called the resistance per square and is expected in ohms
per square, because p/d has the dimensions of ohms.) If we express p by
p=m/ne²t, then Rq=m/ndet. Suppose now that the minimum value of the
collision time is determined by scattering from surfaces of the sheet, so that
Td/v, where v is the Fermi velocity. Thus the maximum surface resistivity is
Rmvp/nd²e². Show for a monatomic metal sheet one atom thickness that

In the last column in the data table, it says that it's about voltage(v) divided by current(A) is equal to ohms so V/A = ohms.
So if it's V/A and if you divide them to get the slope it's (y2-y1)/(x2-x1) then shouldn't V be the y value and A be the x value?
And can you also try to use a line of best bit instead of drawing the line through each dot?
