How do you find the slope and y intercept for x+2y=4 ?

May 27, 2015

The slope intercept form for a linear equation is
$y = m x + b$
where $m$ is the slope and $b$ is the y-intercept.

Re-writing $x + 2 y = 4$

$2 y = - x + 4$

$y = \left(- \frac{1}{2}\right) x + 2$
which is slope-intercept form
with slope $\left(- \frac{1}{2}\right)$ and y-intercept $2$
