Finding resistance in a resistor?

[ninjadrummer8]

Homework Statement

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.)

Homework Equations

R=V/I

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.
