I would rearrange the equation to actually "see" the slope, as:
$2 y = - x - 2$ $2y=-x-2$
$y = - \frac{x}{2} - \frac{2}{2}$ $y=-x/2-2/2$
$y = - \frac{1}{2} x - 1$ $y=-1/2x-1$
The slope is the numerical coefficient in front of your $x$ $x$ , i.e., $- \frac{1}{2}$ $-1/2$

If you re-write your formula in slope point form:
$y = m x + b$ $y=mx+b$
then the coefficient $m$ $m$ is the slope.

In this case
$x + 2 y = - 2$ $x+2y=-2$
$\to 2 y = - x - 2$ $rarr 2y= -x-2$
$\to y = (- \frac{1}{2}) x - 1$ $rarr y =( -1/2)x -1$
with a slope of
$(- \frac{1}{2})$ $(-1/2)$
