Question

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

Answer 1

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=mx+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`.
