What is the slope of any line perpendicular to the line passing through #(2,15)# and #(10,21)#?
See a solution process below:
First, we need to find the slope of the line going 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:
Let's call the slope of the perpendicular line:
The slope of a perpendicular can be found using the formula:
