Answer 8

Boy this is going to be hard to explain... mmmmmm

Answer 9

Notice that our vertex and focus have the same x-coordinate.
\(\large\rm (\color{orangered}{1},-5)\qquad\qquad (\color{orangered}{1},-8)\)

The two locations are stacked, one above the other.
This is telling us that our parabola will open in the y-direction.that's because our parabola will always open around the focus point. Think of it like a magnet maybe.
