First put each equation in y = mx + b format
x+y = 6
y = -x +6
x+ y = 1
y = -x + 1
Now realize that to have a parallel line, both lines must have the same slope. So, the first , third and fourth lines both have the same slope, ie x +y = 1 and y= -x. So both of these will be parallel to x + y = 6. For a line that is parallel and passes through the origin, y = -x or y = x will be the answer.

x+y=1
y=-x
You just have to pass the x on the other side of the equation. Then you seek which equation has x multiplied by the same number. In this case, it is -1.

Well, the slope is 1 and the y-intercept is 0, so it's y = x, which is the same as x = y.

no its y=-x because you would have to subtract x from both sides
