Yes, y varies directly with x. The constant of variation is -3 so the function rule would be y= -3x

Step-by-step explanation:

If you look at the y values in the table, they are just the x values but multiplied by -3.

-3 x (-3) = 9

4 x (-3) = -12

6 x (-3) = -18

Direct variation can be shown by y=kx, where k is a constant. The resulting function creates a linear graph.

the answer is b.
