Physics 11 please help?

Please help with this question. I have to find Rx using the slope of the graph. R1 resistance is 50 ohm, R2 has a resistance of 100, and the Rx resistance is 100 ohm (they give us the unknown value but you have to find it using the slope and then you compare the actual value to what you got). The graph is Current 1 and then Current x Please help me i am so stuck.

The question specifically asks that I am not simply placing data values from a given row of your table in and then solving the circuit for Rx. You are to determine the mathematic expression for the slope of the line based on your knowledge of the Kirchhoff's and Ohm's laws.

    WHat does the circuit look like? The graph doesn't help without the circuit diagram.
