Consider Paulina Jordan's following linear + programming formulation: 100- Minimize $1X1 + $2X2 90- 1X1 + 3X2 2 90 (C 1) 80- 8 X1 + 2X2 2 160 ( C 2 ) 70- C4 3X1 + 2X2 2 120 ( C 3 ) 60- 1X2 S 70 (CA) 50- X1 , X2 20 a) On the graph on right, constraints C1, C2, C3, and C4 have been plotted. Using the point drawing tool, plot all the corner points for the feasible area. O- C2 C3 C1 10 20 30 40 50 60 70 80 90 100 X1
