What is the slope of a line perpendicular to the line containing the points (4,-7) and (5,-1)\? Express your answer as a common fraction.
+36916 m = slope between the two points
= ( -7 - -1) /(4-5) = -6/-1 = 6
perpindicular slope = - 1/m = - 1/6
+36916 m = slope between the two points
= ( -7 - -1) /(4-5) = -6/-1 = 6
perpindicular slope = - 1/m = - 1/6
