# What is the slope of the line perpendicular to y=-3/7x+1 ?

$= \frac{7}{3}$
$y = m x + c$ Where $m$ is the slope
Hence the slope of the line Perpendicular to the line is $= - \frac{1}{m}$
In the equation $y = - \frac{3}{7} x + 1$ Slope $= - \frac{3}{7}$
Hence the slope of the line Perpendicular to the line is $= \frac{7}{3}$
