What does it mean if two linear equations are parallel?

Back

Two linear equations are parallel if they have the same slope but different y-intercepts, meaning they will never intersect.

What does it mean if two linear equations are perpendicular?

Back

Two linear equations are perpendicular if the product of their slopes is -1, meaning they intersect at a right angle.
