Find the equation of the parabola that has directrix on the line
b) y=9 and cuts the x-axis at -11 and 5
d) x=-5 and cuts the y-axis at -3 and 5

I've already found the equation through an educated guess via desmos but I don't exactly know how to get it
answer for b) (x+3)^2=-16(y-4)
d) (y-1)^2=4(x+4)
