Answer
Therefore the slope is $m=-0.5$
The y-intercept is $2$.
The graph is attached below.
Work Step by Step
The slope of the line can be obtained by looking at the coefficient of $x$ in the slope-intercept form$y=mx+b$, where the coefficient of $x$ is the slope.
$x+2y=4$
$2y=-x+4$
$y=\frac{-x+4}{2}$
$y=-0.5x+2$
Therefore the slope is $m=-0.5$
At the y-intercept the x-coordinate of the point is $x=0$. Therefore we can calculate the y-coordinate by plugging 0 to $x$ in the equation:
$x+2y=4$
$0+2y=4$
$y=2$
The y-intercept is $2$.
