Question

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

Answer 1

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

Answer 2

and this formula is for common form for standard form:

Answer 3

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

Answer 4

i dont understand all this caculator stuff

Answer 5

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

Answer 6

ok,meybe i can't explain that,

Answer 7

lol

Answer 8

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.

Answer 9

screw it. i already submitted. thanks for trying
