Parallel and Perpendicular Lines

Two lines that are parallel will have ...

• Slopes that are opposite reciprocals

• No slope

• Slopes that are the same

• Slopes that don't match

Two lines that are perpendicular lines have ...

• Slopes that are negative reciprocals

• No Slope

• Slopes that are the same

• Slopes that switch the numbers
