Question 104032: Determine which two equations represent parallel lines.
(a) y = 9x – 7 (b) y = –9x + 7 (c) y = 9x + 3 (d) y = -1/9x – 7
I have no idea even how to begin to figure this out.

parallel lines have the SAME slope ... the equations are in slope-intercept form
so the two where the x terms have the same coefficient are the ones you want
