Match the solution region of the following system of linear inequalities with one of the four regions shown in the figure. Identify the unknown corner point of the solution region. x + 3y s 15 2x + y 2 10 x 20 y 20 Ay O region Ill region IV O region I O region ll (0, 10) (0.5) IV (15,0) X (0,0) (5,0)The coordinates of all of the corner points are given on the graph except one corner point. What are the coordinates of the remaining corner point? Ay (x,y) = (0 (Type an integer or a fraction.) (0, 10) (0,5) IV (15,0) X (0,0) (5,0)
