Question

How do you find the slope of the following line, `x+2y= -2`?

Answer 1

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

Answer 2

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

In this case
`x+2y=-2`
`rarr 2y= -x-2`
`rarr y =( -1/2)x -1`
with a slope of
`(-1/2)`
