# How do you find the slope and y intercept for: x-y = -7?

Oct 20, 2015

The slope is $1$ and the y-intercept is $7$.

#### Explanation:

$x - y = - 7$ is in the standard form for a linear equation. The slope intercept form is $y = m x + b$, where $m$ is the slope and $b$ is the y-intercept. In order to convert from standard to slope intercept form, solve the standard form for $y$.

$x - y = - 7$

Subtract $x$ from both sides.

$- y = - 7 - x$

Multiply both sides times $- 1$.

$y = 7 + x$

Rearrange.

$y = x + 7$

The slope is $1$ and the y-intercept is $7$.
