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...
They want me to rewrite both in slope-intercept form, then find out if they are parallel or perpendicular.
x - y x + y
----- = ----- - 1
7 = - ( x - y ) + 4y
I would really and truly appreciate any and all help with this...i just don't know what to do
thanks so much,
