okay okay wait wait...
I solve y=a(squared) and y=9*x(squared) - a --- to get two equations
Also when x=0 for the parabola, y=-a right?
Uh okay...could you tell me then what I should do?
OHHH I made a mistake in the diagram...y is not -0.3 ... y=-3
I just drew a diagram in ms paint...

I just assumed that a=3 ... But I still don't get it
