find the slope if any:

x+8y=16

x+0=16

x=16

0 +8y=16

8y=16

8y/8=16/8

y=2

this is the part that loses me:

0-2=-2

16-0=16 -2/16=-1/8 is this correct? If not can you help me?

Put the equations into slope-intercept form:

y = mx + b

m = slope

b = y intercept

For your first problem...

subtract x from both sides

x + 8y = 16

8y = -x + 16

divide both sides by 8

y = -(1/8)x + 2

So, the slope is -(1/8)

I am not sure why you set y to 0 in your solution. That will give you the x intercept, but not the slope.
