What are perpendicular lines?
Back
Perpendicular lines are lines that intersect at a right angle (90 degrees). Their slopes are negative reciprocals of each other.

FLASHCARD QUESTION
Front
How do you determine if two lines are perpendicular?
Back
Two lines are perpendicular if the product of their slopes is -1.

Back
The slope (m) is the coefficient of x in the equation, representing the steepness of the line.
