Example Question #1 : How To Find The Slope Of A Perpendicular Line
A line is defined by the following equation:
What is the slope of a line that is perpendicular to the line above?
The equation of a line is where is the slope.
Rearrange the equation to match this:
For the perpendicular line, the slope is the negative reciprocal;
therefore
