Example Question #63 : Parallel Lines
Which set of equations represents parallel lines?
Parallel lines are lines that never intersect. This is a result of having the same slope, creating equal distance between points on the two lines.
The student would run through the sets of equations putting them into 
The only set of equations with the same slope is
