## Intermediate Algebra for College Students (7th Edition)

$Slope: m=-\frac{A}{B}$ $y-intercept: b=\frac{C}{B}$
$Ax+By=C$ $By=-Ax+C$ Divide by B. $y=-\frac{A}{B}+\frac{C}{B}$ Now equation of line is in form $y=mx+b.$ Since the slope is $m$ and the y-intercept is $b$, $Slope: m=-\frac{A}{B}$ $y-intercept: b=\frac{C}{B}$
