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

Re-writing $x + 2 y = 4$ $x+2y =4$

$2 y = - x + 4$ $2y = -x + 4$

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