+13 Line A passes through points (6,8) and (1,-7). Line B is perpendicular to Line A. Line C is perpendicular to Line B. What is the slope of Line C?
+9479 slope of Line A = [ y2 - y1 ] / [ x2 - x1 ]
slope of Line A = [ -7 - 8 ] / [ 1 - 6 ]
slope of Line A = [ -15 ] / [ -5 ]
slope of Line A = 3
Line A is perpendicular to Line B and Line C is perpendicular to Line B. Since Line A and Line C are both perpendicular to Line B, Line A and Line C must have the same slope.
slope of Line C = 3
