What is the slope of any line perpendicular to the line passing through #(-12,14)# and #(-1,1)#?
See the solution process below:
First, find the slope of the line defined by 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:
Let's call the slope of the perpendicular line
The formula for
Substituting the slope we calculated for
The slope of a perpendicular line is
