# How do you find the slope and intercept of x+y=-5?

Mar 28, 2018

Slope = -1
y-intercept = -5

#### Explanation:

$x + y = - 5$

If you rearrange it to standard form $y = m x + b$ (m being the slope and b being the y-intercept)

$y = - x - 5$

$m = - 1$
$b = - 5$

#### Explanation:

First, the equation needs to be rewritten into Slope-Intercept Form, which is $y = m x + b$, where "m" is the slope, and "b" is the y-intercept, by solving for y.

$x + y = - 5$
$y = - 5 - x$
$y = - x + 5$

To find the slope and y-intercept of any equation in Slope-Intercept Form, your "m" value will represent slope, and your "b" value will represent the y-intercept.

In this equation: $y = - x + 5$, there is no written number for the m value, but x is still technically being multiplied by 1, so "m", or slope, can be represented with "-1".

Since there is a value for "b", or y-intercept, it can be represented with 5.
