#### Answer

Slope: $2$
$y$-intercept: $(0,-10)$

#### Work Step by Step

Rearrange the equation into slope-intercept form.
$4x-2y=20$
$-2y=-4x+20$
$y=2x-10$
The slope is the coefficient of $x$, and the constant term that is added is the $y$ value in the $y$-intercept of $(0,y)$.
Slope: $2$
$y$-intercept: $(0,-10)$
