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

Sep 24, 2015

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

$y = m x + q$.

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 $q = - 2$.
