What is the solution of V1-3x = x+3?
60
x = 8 or x = -1
X=8
x = -1
no solution

With the given focus of (-9,6) and directrix of x=-1 we know that the equation for this parabola would be :
-16x-80=(y+1)^2
The vertex would be :
(-5,-1)
Eccentricity 1
Axis of symmetry y=-1
x intercept (-8/16, 0)
No y intercept
And the graph pic of parabola is in attached pic
