(3.7) Parallel and Perpendicular Lines
Slope and Parallel Lines
Slopes of Parallel Lines: 1) If two nonvertical lines are parallel, their slopes are equal.2) If the slopes of two distinct nonvertical lines are equal, the lines are parallel.3) Any two vertical lines are parallel.
Slope and Parallel Lines
Are lines l and m parallel?
(-2,-4) (1,-4)
(1,5)

l m
Slope and Parallel Lines
Which of the following lines are parallel?
A : y 1
3x 1
D : 4y 12x 20
C : y 3x 1
B : 4y 12x 20
Slope and Parallel Lines
Write an equation in point-slope form for the line parallel to 3x + y = 4 containing the point (-1,2).
Slope and Perpendicular Lines
Slopes of Perpendicular Lines: 1) If two nonvertical lines are perpendicular, the product of their slopes is -1.2) If the slopes of two lines have a product of -1, the lines are perpendicular.3) Any horizontal line and vertical line are perpendicular.
