    1. The problem statement, all variables and given/known data

    graph the following:

    2. Relevant equations


    3. The attempt at a solution

    So far I've gotten to [tex](x+1)^2 = -4(y-2)[/tex]
    If that's right, I have p = -1 and v = (-1 , 2) and directrix: y=2. Could someone double check me to see if I'm doing it right?

    No, that's completely wrong! What happened to the y2 in the original equation? Try completing the square in y again!
