Expert Answer:

1) It is a straight line.
 
2) Resistivity of a conductor is a property of a material and temperature. It does not depend on geometry.
    Resistance is directly proportional to length and inversely proportional to cross-sectional area.
    Thus:
    a) The resistance is doubled.
    b) it is doubled
    c)  it is halved
