Either table a or b shows a proportional relationship. look at picture

Table B shows the proportional relationship.

That's because since it keeps the base ratio (pretend like its 1/3) 1/3 even when its negative, it is still consistent. With Table A, you dont have the same proportions, you have different ones. That's why Table B is the answer.

Is it b? i’m not too sure cause i haven’t referred back to economics for quite a long time now.
