Answer:
<em>1, 4.5</em>
Step-by-step explanation:
for midpoint
x₁ = -2, y₁ = 0
x₂ = 4, y₂ = 9
for midpoint
(x₁+x₂)/2 , (y₁+y₂)/2
(-2+4)/2 , (0+9)/2
2/2 , 9/2

Step-by-step explanation:
Since we have a vertical directrix, the equation of the parabola is

Where p is the distance from the vertex to the directrix.
or the distance from the vertex to the focus.
Since we have a sideways parabola, let use the point for the directrix is (-6,0). So let find the midpoint of (-6,0) and (6,0). That would be our vertex.


So our vertex is (0,0).
So our equation become

The distance from the focus and directrix is 6.
So p=6.

So p is 6.
Since p is 6,
