<font face="Times New Roman" size="+2">


Perpendicular lines have negative reciprocal slopes.  Determine the slope of the given line, then calculate the negative reciprocal of this slope.  Use the calculated slope and the given point in the point-slope form of a line:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ y\ -\ y_1\ =\ m(x\ -\ x_1) ]


where *[tex \Large \left(x_1,y_1\right)] are the coordinates of the given point and *[tex \Large m] is the calculated slope.
