$perpendicular slope = 3$ $"perpendicular slope "=3$

Explanation:

$Given a line with slope m the the slope of a line$ $"Given a line with slope m the the slope of a line"$
$perpendicular to it is$ $"perpendicular to it is"$

$m_{perpendicular} = - \frac{1}{m}$ $m_(color(red)"perpendicular")=-1/m$

$\Rightarrow m_{perpendicular} = - \frac{1}{- \frac{1}{3}} = 3$ $rArrm_("perpendicular")=-1/(-1/3)=3$
