What is the definition of parallel lines in terms of slope?

Back

Parallel lines have the same slope but different y-intercepts.

Front

What is the definition of perpendicular lines in terms of slope?

Back

Perpendicular lines have slopes that are negative reciprocals of each other.

Front

How can you determine if two lines are parallel using their slopes?

Back

If the slopes are equal, the lines are parallel.

Front

How can you determine if two lines are perpendicular using their slopes?

Back

If the product of their slopes is -1, the lines are perpendicular.
