What is the slope of any line perpendicular to the line passing through #(-6,-4)# and #(7,-12)#?
The perpendicular slope would be
The slope a line that is perpendicular to a given line would be the inverse slope of the given line
The formula for the slope of a line based upon two coordinate points is
For the coordinate points
The slope is
the perpendicular slope would be the reciprocal (-1/m)
