The linear equation x + y = -5 is in a nice "general" form sometimes referred to as Standard Form: Ax + By = C. You can find the slope by doing one of two different things:

- Solve for y = (put the equation into slope-intercept form) or
- Use a "formula"

If you actually solve the Standard Form itself for y = ...

Ax + By = C

(subtract Ax from both sides)

By = -Ax + C

(divide both sides by B)

So, the slope for your equation x + y = -5 would be

This is the same way that you would put your equation into slope-intercept form:

which helps you to identify both the slope (-1) and the y-intercept (-5).
