Question 71228: i need to find the slope of a perpendicular line through (5,-4) and (4,2)
Answer by checkley75(3666) (Show Source): You can put this solution on YOUR website!
find the slopeof a line through these two points thus:(y2-y1)/x2-x1) or
(2+4)/(4-5)
6/-1=-6 is this slope.
thus any line perpendicular to this line is the negative reciprical of -6 or 1/6
