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

Oct 4, 2015

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 $7$.
