Ask questions in the comment section if you have questions. I'm happy to help! <3

Step-by-step explanation:

What the question is telling you is that x and y and proportional, almost like a ratio.

x : y

-3 : 6

Now we have to find y when x is four.

-3 : 6

    to

4 : y

Let's create a proportional equation...

(-3 / 6) = 4 / y

- 1 / 2 = 4 / y

What can we divide by four to create -1/2?

y = -8.
