1. In each graph, the two lines are parallel to each other.
2. Each set of equations have the same slope.
3. Equations that have the same slope as each other will always be parallel to each other.
Hang on ,it is already proven through given .
So The proof is of one line only
- ray FEH bisects <DFG (Given)
Hence proved .
The value of 
in terms of s will be
<h3>What is Logrithm?</h3>
A quantity representing the power to which a fixed number (the base) must be raised to produce a given number.
Here we have the expression:-
So in terms of s the expression will become:-

I line that is perpendicular is a line with reversed slopes like 2/1 is perpendicular to -1/2. So find the slope by getting the y by itself and reverse it. Remember to switch the signs too! P.S. if you don't know how to get the y by itself just take and subtract 3x from -5y and -4 then divide by 5. Hope I helped!
