If the link does not work (it works for me!), copy and paste your question into the "search" bar at the top. Then, it will bring you to a google page. From there, just press enter (or whatever key you use), and you will end up with a whole page of web2.0 answers to your question!

:)

(You can PM me for a more in depth explanation if you'd like!)

Here ...I copied and pasted the info at the link:

x + 3y = -5.      is tha same as    y = -1/3 x - 5/3     slope, m = -1/3

parallel line is of the form   y = -1/3 x + b

sub in the given point      2 = -1/3 (-7)  + b     shows b = -1/3

so line eq becomes       y = - 1/3 x -1/3

re-arranged                  y + 1/3 x = -1/3        multiply by 3

x + 3y = - 1      now you can calc  B-A
