If two lines are perpendicular to each other, their slopes
are negative inverses of each other.
Thus,
[tex]\boldsymbol{\sf{Slope\:of\:this\:line=4}}}[/tex]
[tex]\boldsymbol{\sf{Negative \ Inverse=-\displaystyle\frac{1}{4}}}[/tex]. 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.
