Perpendicular lines have slopes that are opposite reciprocals.

This means we take a number, flop it over, and change its sign.

Here we have the number:-

$\boxed{(7)/(3)}$

Flop it over:-

$\boxed{(3)/(7) }\longleftarrow\sf{the~numerator~and~denominator~switch~places}$

Change its sign:-

$\boxed{-(3)/(7)}$

Hence, the slope of line e is:-

$\bigstar{\boxed{\pmb{Slope=-(3)/(7)}}}$

Hope everything is clear; if you need any explanation/clarification, kindly let me know, and I will comment and/or edit my answer :)
