What is the slope of a line parallel and perpendicular to the line going through: #(-7, -3)# and #(6, 8)#?
See the entire solution process below:
First, find the slope of the line going through the two points. The slope can be found by using the formula:
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:
