Lines that are PARALLEL TO EACH OTHER have the same slope. For example, y= x + 5 and y = x+ 7 are parallel to each other. Lines that are parallel to each other does not have any common solutions because they will never intersect, regardless of what point in the coordinate system you choose the evaluate it.
