The given equation is x+2y=-2
2y=-x-2
y=(-1/2)x+(-1)
Comparing with y=mx+c we get slope=(-1/2)

Solve it for y:

  x + 2y = -2
 -x           - x
----------------
     2y = -2  - x
     2y = -x  - 2
     2y = -1x - 2
     expr%282%2F2%29%2Ay%22%22=%22%22expr%28%28-1%29%2F2%29%2Ax-2%2F2 <--divide ONLY the numbers by 2, not the letters:
      y = expr%28-1%2F2%29%2Ax-1

Now compare that to

      y = m*x + b  and see that m = -1%2F2, which is the slope.
