How to answer this physics question?

The current in a variable resistor to which a given voltage is applied is found to vary inversely with the resistance. What is the shape of the current resistance curve? How could these variables be changed in order for a straight-line graph to be obtained?

    I = E/R, so yes, you get a hyperbola.

    use conductance G = 1/R

    then I = EG which is linear
