So I am saying I drew it like this http://www.s-cool.co.uk/a-level/assets/learn_its/alevel/physics/Resistance/internal-resistance-emf-and-potential-difference/Finding%20the%20internal%20resistance.gif Does it make a difference to the graph that were measuring V at a different point

I drew a line that made a triangle from the V axis to the I axis, so when the current was at its highest V was 0 and when V was at its highest I was 0, so it was a negative slope. I used emf= V+Ir and rearranged it go get emf - Ir = V. I am confused at wether the graph should be the a...

need help with this question, is the gradient negative or positive since the voltmeter is over the battery? Here is the image (sorry for making you tilt your heads) https://www.dropbox.com/sh/v6ydqbfrg20whtb/ZWR-r9ZOSH?lst#f:q17.JPG
