What is the equation of a line, in general form, with a slope of -2 and a y-intercept of 8?

x + 2y - 8 = 0
2x + y - 8 = 0
2x - y + 8 = 0

Thanks,@britanyashton  that would be appreciated, and you can just call me Nat. :)

How I would do this- well I remember y=mx+b.
the slope is -2
and the b=8
-2x+8=y
  -y          -y
-2x-y+8=0
I would multiply each side of it by -1 to cancel out that negative sign. 
2x+y-8=0

I haven't done this in forever, but i can almost say that this is right.
