What is the slope of any line perpendicular to the line passing through #(2,-22)# and #(18,-4)#?
First, we need to find the slope of the line passing through the two points in the problem. The slope can be found by using the formula:
Substituting the values from the points in the problem gives:
The slope of the line passing through the two points is
A line perpendicular to this line will have a slope (let's call it
