One of the tables shows a proportional relationship. Graph the line representing the proportional relationship from this table.

x 1 2 3 5

y 2 3 4 6

x 2 4 6 8

y 0 2 3 4

x 0 2 4 6

y 1 3 5 7

x - 2 1 2 3

y - 6 3 6 9

Look at

x - 2 1 2 3

y - 6 3 6 9

and note that every y is found by multiplying the x value above it by 3 (the constant of proportionality). That makes this a proportional relationship. The other tables do not illustrate proportional relationships because there's more than one multiplier in each.
