    Katlin, what did you get for your equation of your line? that is a good starting point.

    First multiply both sides by 3 to get rid of the fraction.

    I just have to put it on a number line using either an open or closed circle

    Yes, but in order to put on a line it should be in the proper equation. Rewrite your given problem so that x is on one side.

    your -6 is correct, but your inequality sign should have been switched.

    so it should be an open circle then instead of a closed circle right?

    What is the difference b/w open and closed?

    < or > means open circle <= or >= means closed circle

    as a hint, closed is "inclusive" so if you have = to also, than it is closed. Your direction is what I was getting you to change....

    correct, so then it would be an open circle right?

    yes - you just had the line going in the wrong direction.....final equation is less than or equal to so therefore your lines goes to the left
