Slope: $-1$
Y intercept: $4$

Rearrange the equation so that it is written in slope intercept form:

$y=mx+b$

Where $m$ is the slope and $b$ is the y intercept

$2x+2y=8$

Begin to isolate $y$ by subtracting $2x$ on both sides of the equation

$2y=-2x+8$

Isolate $y$ by dividing both sides of the equation by @2@

$y=-x+4$

Where the slope is $-1$ and the y intercept is $4$
