Equation of parabola from focus and directrix


We have a focus of (7,11) and a directrix of y = -1. We need to use what we know about parabolas to find the equation. I want to apologize for the shaky camera work, as well as the sometimes (well mostly) blurry view. Hopefully my talking walks you through the process well enough.
