Given two points, finding the equation of the line perpendicular to it
In this video series I show you how to determine a line that is parallel or perpendicular to another line through a point.
A race! Oh, don't forget to stretch guys. Parallel lines always stay the same distance apart, so they will never cross, no matter how long they go on for. And that's why they're used in races. Ready ...
If lines are perpendicular to each other then \({m_1} \times {m_2} = - 1\) conversely if \({m_1} \times {m_2} = - 1\) then the lines are perpendicular to each other.
