I need your help to answer the below questions as you can see below:

3. Let R = {(1, 1), (1, 4), (2, 3), (3,2), (3, 3), (4, 1), (4, 4)} bearelation onaset A = {1, 2, 3,4, }. Represent this relation with the help of a zero-one matrix and show that this relation is symmetric but not an equivalence relation. 4. Show that the divisibility relation R : {(a, b) | a divides b is. 0|b}, is a partial ordering on the set of positive integers Z+. 5. How many edges are there in a graph with ten vertices each of degree 6'? 6. Draw the graph using the following adjacency matrix A with respect to the vertices a, b, c,d: OIIIIII HOODt IICDCDII CHIto
