Let's graph these lines: * I'm using y = mx + b stuff to graph them!


Sal determines which pairs out of a few given linear equations are perpendicular.


Review the basics of parallel and perpendicular lines. Identify and draw parallel and perpendicular lines in some practice problems.


Perpendicular Lines. more ... Perpendicular Lines. Lines that are at right angles ( 90°) to each other. Try for yourself: See: Parallel Lines. Next.


Using the slope intercept formula, we can see the slope of line p is ¼. Since line k is perpendicular to line p it must have a slope that is the negative reciprocal.


Demonstrates how to determine if slopes are for parallel lines, perpendicular lines, or neither. Explains why graphing is not generally helpful for this type of ...
