Two lines that coincide look and act exactly like a single line. If you have one straight line, there are an infinite number of planes in which it lies.
false
No. The planes must either coincide (they are the same, and intersect everywhere), be parallel (never intersect), or intersect in exactly one line.
yes, if it happened that they all intersected at the same point. otherwise,three lines, assuming they are non-parallel or they do not coincide, would have at most two intersection points (one for each other line)
The graphical solution of two straight lines, if it exists, is a single point. If such a point exists, its mean will be itself.
