    yeah the second one looks like \(y=mx+b\) for sure, what is \(m\)?

    for the slope of \[2x+2y=4\] you can solve for \(y\) in two steps to get the slope

    subtract \(2x\)then divide by \(2\) \[2x+2y=4\\ 2y=-2x+4\\ y=-x+2\]

    so they are parallel because they have the same slope since m in this problem also is -1? @satellite73
