Finding resistance in a resistor?

1. The problem statement, all variables and given/known data

Basically, this "battery" is actually a variable voltage source. The current is raised and the voltmeter measures the voltage in the resistor. What is the resistance in the region that the current goes from 1-4 Amps? (BTW, the red line is a best fit line.)


2. Relevant equations
R=V/I


3. The attempt at a solution
Ok, well since this is linear, the slope of this line is actually V/I, so would the slope of the line be the resistance?

Yes it would be the slope of the line.
