Perpendicular lines are a bit more complicated. If you visualize a line with positive slope (so it's an increasing line), then the perpendicular line must have negative slope (because it will be a ...
Sections: Slope-intercept form, Point-slope form, Parallel and perpendicular lines ... There is one other consideration for straight-line equations: finding parallel and perpendicular lines.
Two lines are perpendicular if the product of their slopes is -1. Also, the two intersecting lines form right angles.
In geometry, two lines or planes (or a line and a plane), are considered perpendicular (or orthogonal) to each other if they form congruent adjacent angles. The term may be used as a noun or adjective. Thus, referring to Figure 1, the...
