A line between 2 vertices in Graph theory is called an edge or an arc, although arc is usually used to denote a directed edge.

A line of symmetry divides a figure into two matching halves.
No. Since the graph is simple, none of the vertices connect to themselves - that is, there are no arcs that loop back on themselves. Then the two vertices with degree 6 must connect to all the other vertices. Therefore there can be no vertex with less than two arcs [ to these two vertices]. So a vertex with degree 1 cannot be part of the graph.
