Answer:
LHS.= Sin 2x /( 1 + cos2x )
We have , sin 2x = 2 sinx•cosx
And. cos2x = 2cos^2 x - 1
i.e . 1+ cosx 2x = 2cos^2x
Putting the above results in the LHSwe get,
Sin2x/ ( 1+ cos2x ) =2 sinx•cosx/2cos^2x
=sinx / cosx
= Tanx
.•. sin2x/(1 + cos2x)= tanx
Step-by-step explanation:

Therefore, the slope of the line is 1. In case if you want to know the equation.

Therefore, the equation is y=x+10 by substituting the (-6,4) or we can substitute (6,16) too.

It's the same, you can use any orders given.
Overall, the slope is 1 and the equation is y=x+10
