Hello everyone... I'm new here, first post and all...

So I was wondering if someone could help me out with the following equation... I'm using MyMathLab and have exhausted all of my tries, otherwise I wouldn't have asked here... Anyway, here's the equation...

The following equation is the standard form of a line. Solve for y.

3x-9y=18

(Use integers or fractions for any numbers in the expression. Simplify your answer.)

Here's the work that I did...

3x-9y=18

-9y=18-3x

y=18-3x/-9

y=-2-3x/-9

y=-2-3/9x

Final answer: y=-2-1/3x

However, my answer is wrong... Can someone please guide me to what I am doing wrong?
