Question

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?

Answer 1

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
