12.6 Parallel and perpendicular lines
Parallel and perpendicular lines
In this section, we will look at various kinds of questions related to parallel and perpendicular line equations. For instance, we will try to look for the slope of a line that is parallel and perpendicular to a given equation, to figure out if a given pair of line equations is parallel, perpendicular, or neither, and to find the parallel and perpendicular line equations of a given line and a pass through point.
