Work Step by Step

We are told that the focus is below the given vertex, thus, $ p$ is the negative of the distance between the two points. So, $p=-|2-0|=-2$ Since the vertex and focus have the same x-coordinate, the parabola must have a vertical axis. Now, we will write the equation for the parabola that has a vertical axis using the vertex and $p$. $(x-h)^2=4p(y-k)$ $\implies (x+1)^2=-8(y-2)$
