Question

How do you find the slope and y-intercept for the line `x + y + 2 = 0`?

Answer 1

Slope: `-1`
`y`-intercept: `-2`.

Explanation:

To find the slope and the `y`-intercept of a line, you need to put it in the form

`y=mx+q`.

Then, `m` will be the slope and `q` the intercept.

In your case, it is very simple, because you only need to isolate the `y`, bringing the term `x+2` on the right hand, and thus changing its sign into `-x-2`. Once in the form `y=-x-2`, you'll have `m=-1` and `q=-2`.
