1. Make a figure that illustrates the feasible set in R².
2. Provide some integers n, m € R and matrices c E R", A € Rmxn, and b € Rm such that it is in
standard form maxxER cx s.t. Ax = b and x > 0.
3. On your figure, identify each vertex x € R² and its corresponding basis (possibly more than one)
B of the columns of A so that N = 0 where N = {1,...,n} \ B.
4. Solve the linear program using the simplex algorithm in tableau form. Report the iterations on
your figure.
5. Use the dual simplex algorithm in order to find a solution if the constraint x₁ < 2 is added.
