y-intercept is 4

Given: $2y=8$

Divide both sides by 2

$y=4$

Notice there are no $x$ terms so write it as:

$y=0x+4$

Compare to: $y=mx+c$ where $m$ is the gradient and $c$ is the y-intercept

$y=0x+c$
$y=0x+4$

The slope ( $m$ ) is $0$ from $0x$ so it is parallel to the x-axis.

y-intercept $=c=4$
