I cannot figure out homework! Im supposed to tell if each describes a parabola and if so, determine the vertex, focus, and latus rectum length.

Help! I cannot figure out homework! Im supposed to tell if each describes a parabola and if so, determine the vertex, focus, and latus rectum length.

1. (x-1)^2=4(y-4)^2
2. 12(x-2)=(y+2)^2
3. x^2=-4y^2
4. -2(x+8)=(y-1)^2
5. x^2-4x-y+1=0

for these I have to do the same thing and directrix

1. 4(x-3)=(y+2)^2
2. 6x=y^2
3. 8y=(x-3)^2-16
4. y^2+4x-2y+9=0
