y-intercept $=-4$
x-intercept $=-8$

Given -

$y= -1/2x-4$

To find $y$ intercept put $x=0$ in the equation

At $x= 0; y = -1/2(0)-4= -4$

Alternate way -

The given equation in the slope-intercept form of $y=mx+c$ Where $c$ is y-intercept.

You can straight away state $-4$ is y-intercept

To find the $x$ intercept put $y=0$

$-1/2x-4=y$

$-1/2x-4=0$

$-1/2x=0 +4$
$-1/2x=4$

$x=4(-2/1)=-8$

$x=-8$
