SOLUTION: Find the minimum and maximum values of the objective function subject to the given constrants. Objective function: C= 2x + 3y Constraints: x>0 y>0 x +y <

Question 530477: Find the minimum and maximum values of the objective function subject to the given constrants. Objective function: C= 2x + 3y
Constraints:
x>0
y>0
x +y < 9
I also have to graph this and I just don't get how to even start this type of a problem.

Find the minimum and maximum values of the objective function subject to the given constrants. Objective function: C= 2x + 3y
Constraints:
x>0
y>0
Comment: These two conditions tell you the answers are in the 1st Quadrant.
-----------------------------
x +y < 9
Graph the boundary line: y = -x+9
Solutions points are below the boundary line and in the 1st Quadrant.

====
The vertices you need to check are (0,0),(0,9),(9,0)
(0,0): 2*0+3*0 = 0 (minimum)
(0,9): 2*0+3*9 = 27 (maximum)
(9,0): 2*9+3*0 = 18
