# What is the slope of any line perpendicular to the line passing through #(-12,14)# and #(-1,1)#?

##### 1 Answer

See the solution process below:

#### Explanation:

First, find the slope of the line defined by 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:

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
