I always learned Ohm's law as, "V = I*R". You know, over the handful of classes that included it at some point. When you say 'Ohm's law,' my brain says 'vee-equals-aye-arr.' So...I did check wikipedia first to make sure I wasn't having a stroke, but I think 'V=I/R' is a typo.

Anyways, that does seem fairly self-explanatory. More volts means more current with the same resistance. More resistance means less current with the same voltage.
