# What is the slope of a line parallel and perpendicular to the line going through: #(-7, -3)# and #(6, 8)#?

##### 1 Answer

See the entire solution process below:

#### Explanation:

First, find the slope of the line going through the two points. The slope can be found by using the formula:

Where

Substituting the values from the points in the problem gives:

A line parallel to this line will have the same slope as this line. Therefore, the slope of a parallel line will be:

Let's call the slope of a perpendicular line

Therefore, the slope of a perpendicular line is:
