# What is the slope of any line perpendicular to the line passing through #(7,23)# and #(1,2)#?

##### 1 Answer

See the entires solution process below.

#### Explanation:

First, we need to determine the slope of the line passing through the two points. The slope can be found by using the formula:

Where

Substituting the values from the points in the problem gives:

So the slope of any line perpendicular to this line, let's call this slope

Therefore, for the problem:
