Answer:
Not proportional.
Step-by-step explanation:
A proportional relationship is a relationship which crosses through the origin (0,0) and which has a proportional constant. We can determine this either by finding (0,0) where x=0 and y=0 in the table or by dividing y/x. None of the tables contain (0,0) so we will divide y by x. We are looking for a table which when each y is divided by its x we have the same constant appearing.
![\frac{2}{1} \neq \frac{3}{2} \neq \frac{4}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B1%7D%20%5Cneq%20%5Cfrac%7B3%7D%7B2%7D%20%5Cneq%20%5Cfrac%7B4%7D%7B3%7D)
Though it has a point at the origin, these fractions are not equal. This is not proportional.
