Unit 2 Lesson 3
In Unit 2 Lesson 3 we learned about parallel and perpendicular lines. We learned how to graph them, find their equations, and how to tell if 2 lines are parallel or perpendicular.
- Parallel Lines -
- Same slope
- Different Y-Intercept
- Lie in same plane
- Never meet
- Perpendicular lines -
- Slopes are negative reciprocals
- Can have same or different Y-Intercepts
- Lie in same plane
- Intersect at a 90° angle
