Your plan on going golfing this weekend with a friend. You can either go to your favorite course which is 14 miles north of your house or your friend’s favorite course which is 14 miles south of your house. Write an absolute value inequality that represents all the distances you may be from your house.
You dont need an absolute value as you cannot have negative distances in real space.
x < 14
The only thing that changes is your direction (or vector). Therefore, any negative length (or positive) would be relative to a reference, unit vector.
In other words, a positive distance in a "negative" direction might be regarded as a negative distance in a positive direction.

Want "extra credit?" Ask your teacher why it has to be an absolute value inequality? Linear distances are never negative.
