Which table shows a proportional relationship between a and b

Answer: B Step-by-step explanation:I first went through starting with A and took 3-9 (since it’s in the first box) I got -6 . You then divide 3 and 9 by -6 and report your answer. I got 3/-6 = -.5 and And 9/-6 = -1.5 I then moved onto 4 and 12, I took the difference 4-12 and got -11. 4/-11 = -0.36 and 12 /-11 = -1.09Since these answers are not the all the same I moved onto BI took 20-25 = -520/-5 = -4 and 25/-5 = -5Next numbers 24-30 = -624/6 = 4 and 30/6= 5 Next number 32-40= -832/-8 = -4 40/-8 = -5( when putting this in fraction form it would be -4/-5 and that turns positive.) making this table proportioned unlike the other ones
