We present two graph theoretic problems whose solutions use elementary yet clever applications of linear algebra. The first problem concerns the existence of a covering of the complete graph on 10 vertices with 3 disjoint copies of the Petersen graph. The second investigates bounds on the number of edges a graph on a fixed number of vertices can have if the graph contains no cycle of length 4.
