A graph with vertices $v_1,v_2,v_3,v_4,v_5$ has adjacency matrix $A=?\begin{array}{lllll}0& 1& 0& 1& 0\\ 1& 1& 0& 0& 0\\ 0& 0& 0& 1& 0\\ 1& 0& 1& 0& 1\\ 0& 0& 0& 1& 0\end{array}?$ 1. What is the order of the matrix $A$ ? order = 2. How many edges does the graph have? answer = 5 3. Is the graph a pseudograph, a multigraph, or a simple graph? answer = 4. What is the degree of vertex $v2?$ degree $=$ 5. What is the degree of vertex $v4$ ? degree $=$
