provide a diagram of w5, the wheel graph with 5 vertices, with the vertices labeled v5 and the edges labled e8.
(a) find a, the adjacency matrix for w5 with your labeling.
(b) find m the incidence matrix for w5 with your labeling.
(c) does an unlabeled graph have a unique adjacency and/or incidence matrix? explain.
(d) if n is an incidence matrix for some graph g, then what can you say about the sum of
the entries in any column of n?
(e) if n is an incidence matrix for some graph g, then what can you say about the sum of
the entries in any row of n?
