# How do you write x+y=4  into slope intercept form?

Aug 9, 2015

$y = - x + 4$

#### Explanation:

slope intercept form is $y = m x + b$
that means that you should try to get $y$ alone on one side

from
$x + y = 4$
we can subtract $x$ from both sides to get
$y = - x + 4$
which is the form you want :)
