Find the distance between the lines with equations -4x+7y+9=0 and y=4/7-9

Question

anonymous · Answer

I THINK this is the formula , but i'm not sure, @ganeshie8  tell me if i'm wrong or not...
$$d = \frac{ |b _{2}-b _{1}| }{ \sqrt{m ^{2}+1} }$$

anonymous · Answer

and this formula is for common form for standard form:

anonymous · Answer

$$d = \frac{ |c _{2}-c _{1}| }{ \sqrt{a ^{2}+a ^{1}} }$$

anonymous · Answer

i dont understand all this caculator stuff

anonymous · Answer

and you should know that these formulas are used for $ \Huge {Straight \; Lines} $

anonymous · Answer

ok,meybe i can't explain that,

lol

If they are parallel lines, the distance between them is a constant. I would think the easiest way to find that distance would be to find the difference between the y-intercepts.
