What is the slope of any line perpendicular to the line passing through #(-15,2)# and #(-10,4)#?
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:
