Answer: third option.

Step-by-step explanation:

By definition, a direct variation function has the form shown below:

$y=kx$

Where k is a constant.

Then, knowing the given points, you can calculate k with the formula for calculate the slope of a line:

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{-4-(-3)}{-12-(-9)}=\frac{1}{3}$

Substituting k into $y=kx$ , you obtain:

$y=\frac{1}{3}x\\\\y=\frac{x}{3}$
