5. Equations of Parallel and Perpendicular Lines

Continue to next subchapter

Exercise 7 Page 160

Parallel lines have the same slope but different $y -$ intercepts. Perpendicular lines have slopes that are opposite reciprocals of one another.

Parallel Lines: $a$ and $c$
Perpendicular Lines: $b$ and $d$

Practice makes perfect

[Concept:Parallel Lines||Parallel lines]] have the same slope but different

y -

intercepts. Perpendicular lines have slopes that are opposite reciprocals of one another. Therefore, to determine if the lines are parallel, perpendicular, or neither, we first need to find their individual slopes using the Slope Formula.
