• X and Y must be on the same side
• A and B may not contain any fractions
• A must always be positive

Parallel LinesTwo non-vertical lines are parallel if and only if their slopes are equal and they
have different y-intercepts.

Two non-vertical lines are perpendicular if and only
if the product of their slopes is – 1.
Perpendicular Lines

Determine if the lines are parallel, perpendicular, or
neither.
