# What is the slope and y-intercept of the line x + y + 2 = 0?

Jul 30, 2015

slope = -1
intercept = -2

#### Explanation:

The standard equation of the line in the slope-intercept form is $y = m x + c$, where $m$ is the slope and $c$ is the intercept.

So our work is to get the equation in this particular form.

$x + y + 2 = 0$
$\implies y = - x - 2$
$\implies y = \left(- 1\right) x + \left(- 2\right)$
This is an equation in the slope-intercept form, and we can compare it with the equation $y = m x + c$ to get $m = - 1$ and $c = - 2$.

(Try and draw a graph, and it would be very clear to you what the negative slope and intercept means.)
