eqn of axis is 2x-y-18=0 (passing trgh (-2,2), (-6,-6))
directrix is prpndiclar to axis so slope =-1/2
vertex is mid point of focus & intersection of directrix & axis
so intersection point comes(2,10)
eqn of directrix comes x+2y-22=0
apply PF^2=PS^2
(x+6)^2 + (y+6)^2 = (x+2y-22)^2/5

I am only one,
But still I am one.
I cannot do everything,
But still I can do something;
And because I cannot do everything
I will not refuse to do the something that I can do.
