Full solution stays hidden until you ask for it.
1. Identify whether directrix is horizontal or vertical.
2. Find midpoint between focus and directrix along the axis.
3. State axis of symmetry and opening direction toward the focus.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Placing vertex at the focus.
