To find the slope of a perpendicular line, take the negative reciprocal of the slope of the given line. (Flip the top and bottom of the fraction and change the sign.) The slope of 3 can be written as 3/1. The slope of a line that is perpendicular is -1/3.
It is simply the arctan transformation of the fraction.
The same rules apply but it might help if you turn the fraction into a decimal.
The slope can be a fraction.
There is no equivalent improper fraction.
