Question 61032: Find the slope of any line perpendicular to the line through points (8, 17) and (9, 9).
Answer by funmath(2933)   (Show Source):
You can put this solution on YOUR website! Find the slope of any line perpendicular to the line through points (8, 17) and (9, 9).
The slope between these two points can be found with the slope formual:
 , m=slope, (x1,y1) and (x2,y2) are the given points.
(x1,y1)=(8,17) and (x2,y2)=(9,9)
Perpendicular lines have slopes that are negative reciprocals of each other. (That mean that they're opposite signs and upsidedown.)
The slope of any perpendicular line through the line created by those two points is:
