Line A passes through points (6, 8) and (1, -7). Line B is perpendicular to Line A. Line Cis perpendicular to Line B. What is the slope of Line C? Algebra Forms of Linear Equations Equations of Perpendicular Lines 1 Answer Vinay K. Dec 5, 2016 Answer: 3 Explanation: Line B is perpendicular on line A and line C is perpendicular on line B. So line A and line C are parallel and will have same slope. Slop of line A = #(y_2-y_1)/(x_2-x_1) = {-7 - (-8)}/(1-6) = (-15)/(-5) = 3# So slope of line C = 3 Related questions How do you determine the equation of a line that is perpendicular to another?
