slope of line

by tanyajoseph » Mon Sep 03, 2007 12:36 pm
Lines k and m are parallel to each other. Is the slope of line k positive?
1) Line k passes thro the point (3,2)
2) Line m passes thro the point (-3,2)

How exactly should we solve these problems?? Like, wht is the difference between parallel or perpendicular lines, how do you identify the slopes, etc..
Thanks for the help

If you dont know the difference between parallel and perpendicular lines you should start studying Geometry before trying these problems.
