Question

What of the following lines is perpendicular to the line passing across the points (1,1) and (-5,-6)?

y = 6/7x + 1

y = -6/7x + 1

y = -6/7x - 1

y = 6/7x - 1

Answer 1

First find slope
(-6-1)/(-5-1) = -7/-6 = 7/6
Perpendicular = opposite sign and reciprocal slope
Slope would be -6/7
It would be anything with slope of -6/7
