4 Chapter 6: Section 5 Parallel and Perpendicular Lines

5 Parallel Lines Lines in the same plane that never intersect Nonvertical lines are parallel if they have the same slope and different y- intercepts. Any two vertical lines are parallel. Lines in the same plane that never intersect Nonvertical lines are parallel if they have the same slope and different y- intercepts. Any two vertical lines are parallel.

6 Example 1 Check to see if the equations are parallel. Check to see if the equations are parallel.

7 Example 2 Write and equation for the line that contains (5, 1) and is parallel to m, slope point

8 Perpendicular Lines Lines that intersect to form right angles Two lines are perpendicular if their slopes are negative reciprocals. Their product is -1. Vertical and horizontal lines are perpendicular. Lines that intersect to form right angles Two lines are perpendicular if their slopes are negative reciprocals. Their product is -1. Vertical and horizontal lines are perpendicular.

9 Example 3 Check to see if the equations are perpendicular. Check to see if the equations are perpendicular.

10 Example 4 Write and equation for the line that contains (0, -2) and is perpendicular to m, slope point
