# What is the slope of any line perpendicular to the line passing through #(2,-22)# and #(18,-4)#?

##### 1 Answer

Any line perpendicular to the line passing through these two points will have a slope of

#### Explanation:

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:

Where

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

Or,
