the ratio will be x = -2y meaning x/y = -2/1 or x:y :: -2:1.

I was asking if having a ratio with a negative number is correct or not.

You will never have a ratio involving a negative quantity on the GMAT.

Sorry for bumping this but found it relevant.

If x and y are integers, what is the ratio of 3y to x?

(2) 4x2 = 9y2

according to the explanation the statement is insufficient since x/y can be + or -. I marked it as sufficient since I thought you are only concerned about the proportions of the numbers and not their exact values.
