We see that the the parabola opens up since directix is below the focus
for an parabolla opening up/down with vetex at (h,k) and the distance from teh vertex to the focus is p the distance from vertex to directex is the same as from focus to directix
from (-5,5) and y=-1 that is a vertical distance of 6 vertex is in the middle 6/2=3 5-3=2 the vertex is at (-5,2) the distance is 3
