How do you write x+2y=4 into slope intercept form?

Aug 11, 2015

$y = - \frac{1}{2} x + 2$

Explanation:

Slope intercept form can be represented as $y = m x + b$
To get an equation into this form, we should try to get $y$ all alone.

From $x + 2 y = 4$
first, we can subtract $x$ from both sides
and get $2 y = - x + 4$
then, we can divide both sides by $2$
to get $\implies y = - \frac{1}{2} x + 2$
which is now in slope intercept form :)
