Answer:
The correct answer would be 12, which isn't one of your options.
Step-by-step explanation:
When finding direct variation, you start with the base equation.
y = kx
Now we can use the initial values of x and y to find k.
-3 = k(18)
-1/6 = k
Now with the value of k, we can model the equation.
y = -1/6x
And we can find the new x by using our new value of y.
-2 = -1/6x
12 = x
