This is confusing me, because I have this experiment where voltage is the variable that is manipulated, and current is the variable that's dependent on voltage. Therefore, that would put voltage on the Hori- axis, and current on the vertical axis, but when you go to find the slope, you should also be finding the resistance also from the slope, but as R=V/I, you can't because Voltage is on the Horizontal axis, and current is on the vertical axis, and obviously Slope is Rise/ Run.

Absolutely not. You can make your axes to be whatever you want them to be. The purpose of graphs is to clarify things; so if it's clearer to make the dependent variable along the X and the independent one up the Y, so be it.
In your case you want a slope dV/dI = R so that means V = f(I) makes sense. That results because V = dV/dI I + b is the straight line equation that determines voltage from I, the current. b = 0 most likely. And that means V = dV/dI * I = R I. QED.

No, I don't think so. Independent variable isn't always taken on x axis. For example, In F-d graph, displacement which is dependent on force is taken on x axis and force which is independent is taken on y axis. Similarly, when graph is plotted for mass spring system. Extension which depends on applied force is taken on x axis but force is taken on y axis. So, it's not universal to always take independent on x axis. It depends on the variables.
