Question

Write a formula for the slope of a line that is perpendicular to the line through the points (x1,y1) and (x2,y2)

Answer 1

The perpendicular slope is the negative reciprical of the given slope

Answer 2

m = \[\frac{ (y2-y1) }{ (x2-x1) }\]

Answer 3

perpendicular slope is:

\[\frac{ -(x2-x1) }{ (y2-y1) }\]

Answer 4

Sweet. Thanks just wanted to double check my answer

Answer 5

\[(y - y1) = \frac{ -(x2-x1) }{ y2-y1 } * (x - x1)\]

Answer 6

Thanks!
