#1**0 **

slope of Line A = [ y_{2} - y_{1} ] / [ x_{2} - x_{1} ]

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
