My bottom teeth seem to be slanted, what would fix this? I think it may be a jaw issue. (photo)

you have two options,the best one is to do braces and to bring that bite to a correct position,the situation is that at the end you will have a good oclusion,but you will still have the same teeth,with the same shape,size and color,and it will take up to 1 year aprox.now if you do not want to have braces or having braces is not part of your plans,
you can have a different alternative solution,which is Smilemakeover,where you will be having a full mouth change in just a couple of days and change your life!,and you will certainly will have also good results with several techniques involved,and you will be changing shape,size and color.
