Answer:
Step-by-step explanation:
The slope of a line perpendicular to another line is the opposite reciprocal of the slope of the other line, meaning if the slope of the other line is
, then the slope of the line perpendicular is
.
Knowing this, we can start to construct the equation for the line:


To solve for
, we plug in the coordinates of the point that we know the line runs through,
:




Therefore, the slope of the line that is perpendicular ot the line provided in the equation is the following:

The 3rd one
You can factor 3 out of each term in the numerator. And then divide it by the 3 in the denominator.
You would have to take 6336 steps because 63360 inches is one mile and that divided by 10 is 6336
