Question

How do you find the slope and intercept to graph `x+y=-2`?

Answer 1

Slope = -1
y-intercept = -2

Explanation:

To find the slope and intercept of an equation you have to put it in Slope-Intercept Form, which looks like: `y=mx+b` with `m` being your slope and `b` being your y-intercept.

To get your equation into Slope-Intercept Form, you must first subtract the `x` so that the `y` is alone on its side of the equal side. Your equation now will look like this:

`y=-x-2`

Your equation is now in Slope-Intercept Form. This means that your `m` value (your slope) is in front of the `x` and your `b` value (your y-intercept) is behind it. This makes your `b` value `-2`, but there's no number for `m`. The equation above is actually the simplified version of the equation `y=(-1)x-2`. Whenever you see a `-` sign, imagine an invisible `1` along with it. So your `m` value is actually a `-1`.

To summarize:

Slope = `-1`
y-intercept = `-2`
