Provide an appropriate response.The optimal strategy for a 2 × n matrix game can be found as follows: obtain n linear functions by finding the inner product of x(t) =  with each of the columns of the payoff matrix A. Graph the n linear functions on a t-z coordinate system. Then  is the minimum value of the n linear functions which will be seen on the graph as a polygonal path. The  of any point on this path is the minimum of the corresponding z coordinates

of points on the n lines. The highest point on the path  is M. Suppose that M has coordinates  What information is given by these coordinates?
