Answer: 1. x = (y - 2)² + 8
3. y = 2(x +9)² + 7
<u>Step-by-step explanation:</u>
Notes: Vertex form is: y =a(x - h)² + k or x =a(y - k)² + h
- (h, k) is the vertex
- point of vertex is midpoint of focus and directrix:
- p is the distance from the vertex to the focus
1)
Now let's find the a-value:
Now, plug in a = 1 and (h, k) = (-8, 2) into the equation x =a(y - k)² + h
x = (y - 2)² + 8

2)
Now let's find the a-value:
Now, plug in a = -1/2 and (h, k) = (1, 10) into the equation x =a(y - k)² + h
***************************************************************************************
3)
Now let's find the a-value:
Now, plug in a = 2 and (h, k) = (-9, 7) into the equation y =a(x - h)² + k
y = 2(x +9)² + 7
