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

graph the following:

2. Relevant equations

$$x^2-4y^2+2x+8y-7=0$$

3. The attempt at a solution

So far I've gotten to $$(x+1)^2 = -4(y-2)$$
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?

Thanks

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