What is the slope of any line perpendicular to the line passing through #(-15,2)# and #(-10,4)#?
The slope of the perpendicular line is
First, we need to determine the slope of the line going through the two points given in the problem.
The slope can be found by using the formula:
Substituting the two points from the problem gives:
The slope of a perpendicular line is the negative inverse, so we "flip" the slope and take its negative:
