Algebra uno check+ help?

So, I've got these problems:
To tell which form the equation is in.

1)2x+8y=-3
I think this one is standard form.

2)y=-5x+8
I think this is slope intercept form.

3)y+4=2(x-6)
I think this is also slope intecept form.

Could somebody tell me if my answers are correct, if not explain why it's not?

Thanks

1. (1), (2) correct.
(3) This is the point-slope form, i.e.
(y-y1)=m(x-x1)
represents a line that passes through point (x1,y1) with a slope of m.
