Please help!!! What is the slope of a line that is perpendicular to this line?
Whitepunk [10]

\frak{Hi!}

\orange\hspace{300pt}\above3

                      <u>If two lines are perpendicular to each other, their slopes</u>

                     <u>are negative inverses of each other.</u>

                     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

\orange\hspace{300pt}\above3

Definition-:

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