Answer:
-1
Explanation:
2x + 2y = 8 is in standard form, you have to convert that by subtracting 2x from both sides so it ends up to be 2y = -2x + 8. Now you have to make y 1 so you divide everything by 2. Now it's y = -x + 4 or y = -1x + 4 and the slope is in front of the x
you find the slope by putting the equation in slope intercept form y=mx+b
so you would subtract 2x and have 2y=-2x+8
then you would divide by 2 to get y be itself so
y=-x+8
So your slope is -1/1
