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

Explanation:

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

$x - y = - 7$ $x-y=-7$

Subtract $x$ $x$ from both sides.

$- y = - 7 - x$ $-y=-7-x$

Multiply both sides times $- 1$ $-1$ .

$y = 7 + x$ $y=7+x$

Rearrange.

$y = x + 7$ $y=x+7$

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