The circuit shown above has a fixed resistor, $R$, connected in series with a variable resistor, $r$, to a $9.0\text{ volt}$ source. There is a voltmeter connected in parallel with the variable resistor.

Which of the following graphs best shows the relationship between the resistance of the variable resistor and the potential difference that is read on the voltmeter? Note: On each graph, the dashed line represents $9.0\text{ volts}$.
