parallel & perpendicular lines help

hey everyone, this is my first post...i hope i can find some help here, as i have searched my math book up and down, only to find no answer.

i am in college algebra, and the section is parallel & perpendicular lines.

the problem i am totally stuck on is this...

Code:

` `

x - y x + y

----- = ----- - 1

3 2

AND

7 = - ( x - y ) + 4y

**They want me to rewrite both in slope-intercept form, then find out if they are parallel or perpendicular.**

I would really and truly appreciate any and all help with this...i just don't know what to do

thanks so much,

ryan
