Slope $m=-2$
Y-intercept $=-8$

If the straight line equation is in the form -

$ax+by+c=0$

(or)

$ax+by= c$ Then the formula for its slope is-

$m=-a/b$

In the given problem -

$m=-2/1=-2$

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

$2(0)+y=-8$
$y=-8$

How do you find the slope and intercept of 2x + y = -82x + y = -8?
