Answer & Step-by-step explanation:

To find if they have a constant of proportionality of 12, use the following:

[tex]\frac{y}{x}=12[/tex]

Divide y by the x value (x,y), and if the remaining equation is true, then that table has a constant of proportionality of 12.*

:Done

*Make sure you check all the values in a table. Sometimes only the first values will have k=12, while the others don't.

**The constant of proportionality is represented by k.
