Perpendicular Lines Lesson

 $2x+y=16$  

 $y=-2x+1$  

 $y=2x-10$  

 $x-2y=-6$  

go down the slide

pull the number off the x and that is your slope

solve for slope intercept first

$\frac{1}{3}$

 $y+5=\frac{-1}{3}\left(x-9\right)$  

 $y-5=\frac{-1}{3}\left(x+9\right)$  

 $y+5=\frac{-1}{3}\left(x+9\right)$  

 $y-5=\frac{-1}{3}\left(x-9\right)$  

$y=\frac{-1}{3}x+8$

$y=\frac{-1}{3}x-8$

$y=\frac{-1}{3}x-2$

$y=\frac{-1}{3}x+2$
