Question

What is the slope and intercept for `x+y=7` and how would you graph it?

Answer 1

Slope: `-1`
Intercept: `7`

Explanation:

First, rearrange the equation to make `y` your subject.

`y=-x+7`

From the equation, you know that the coefficient of `x` is always your slope. So, in this equation `-1` is your slope.

From the equation you would also know that any number behind the `x` is always your `y`- intercept. So your `y`- intercept is `7`.
