# What is the slope of any line perpendicular to the line passing through (-8,2) and (-12,-20)?

$- \frac{2}{11}$
$\frac{- 20 - 2}{- 12 + 8} = - \frac{22}{-} 4 = \frac{11}{2}$
The slope of the line perpendicular to the line passing through (-8,2)and (-12.-20) is the ngative inverse of $\frac{11}{2}$ i.e.$= - \frac{2}{11}$
