Slope Of Parallel And Perpendicular Lines
Akopọ
Two lines can run side by side forever or cross at a perfect right angle, and their slopes tell you which. A single quick comparison of slopes settles whether lines are parallel, perpendicular or neither.
In this lesson you will use the slope to recognize and create parallel and perpendicular lines: parallel lines share a slope, and perpendicular slopes are negative reciprocals of each other.
Awọn Afojusun
- Use the slope conditions for parallel and perpendicular lines, and find the equation of a line parallel or perpendicular to a given line through a given point.
