    So, you know what slope-intercept form looks like, correct?

    -2y=-3x-9 and i divided them all by negative 2 so now it looks like this -2y/-2=-3/-2x-9/-2

    I think you just made a typo, as the x goes wtih the -3, not on the -2.

    and for the slope-intercept form i should get y=-2/3x-3 correct cause i just bring in the y-intercept as stated in the problem.

    That's correct! Let's clean it up so it doesn't look like you are dividing the -2 by 3x. Make it y=-2x/3 -3 instead.
