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

Oct 3, 2015

The slope is $- 1$ and the y-intercept is $- 2$.

Explanation:

$x + y = - 2$

To convert the linear equation in standard form to slope-intercept form, $y = m x + b$, where $m$ is the slope and $b$ is the y-intercept, solve the standard equation for $y$.

Subtract $x$ from both sides of the equation.

$y = - 2 - x$

Rearrange the right hand side.

$y = - x - 2$

The slope is $- 1$ and the y-intercept is $- 2$.
