## Algebra 1: Common Core (15th Edition)

$y=-\dfrac{1}{2}x+4$
The two equations would be perpendicular. Pick two points of the graph $(3,3)$ and $(5,7)$ to find the slope of the graph is $2$. Therefore the slope of the new equation would be $-\dfrac{1}{2}$ because that's the opposite reciprocal of the slope of the graph. Plug into slope form: $y=mx+b$ $y=-\dfrac{1}{2}+4$
