                      If two lines are perpendicular to each other, their slopes

                     are negative inverses of each other.

                     Thus,

                    $\boldsymbol{\sf{Slope\:of\:this\:line=4}}}$

                    $\boldsymbol{\sf{Negative \ Inverse=-\displaystyle\frac{1}{4}}}$. See how this works?

                    We took 4, then took its opposite, and flopped that over

Definition-:

Perpendicular lines are lines that intercept each other at a 90 deg. angle, which is usually called the right angle.
