Answer:

(b) the correct table is marked

Explanation:

Direct variation is characterized by the ratio of y to x being a constant for all values in the table. That constant is the constant of proportionality. For the values in the second table (marked), the ratio is ...

y/x = 8/6 = 12/9 = 16/12 = 4/3

The constant of proportionality is 4/3.
