Answer:

Step-by-step explanation:
1. rewrite the equation in standard form: 
2. find (h,k), the vertex. the vertex is 
3. find the 'focal length' of the parabola - the focal length is the distance between the vertex and the focus. from the vertex we can see that the focal length, p, = 3/2
4. Parabola is symmetric around the y-axis and so the asymptote is a line parallel to the x-axis, a distance p from the
y coordinate which is at
. Set up the equation:

5. substitute and solve:

Answer:
y =8.7
Step-by-step explanation:
y + 8.5 = 17.2
Subtract 8.5 from each side
y +8.5 -8.5 = 17.2 -8.5
y =8.7
