1 Answer
See a solution process below:
Explanation:
The formula for find the slope of a line is:
Where
Substituting the values from the points in the problem gives:
Let's call the slope of a perpendicular line:
The slope of a line perpendicular to a line with slope
Substituting the slope for the line in the problem gives:
