Answer 2.1
Figure D.1 shows the feasible region and the optimum solution. Let z be the objective function z = 8x1 + 6x2. We want to maximize objective function z. We rewrite this function as x2 =
. The slope of this function is –
, and it intersects the x2-axis at (0, z). If we move this function up along the x2-axis while keeping its slope, z increases. On the other hand, if we move it down along the x2-axis, z decreases. As shown in Figure D.1, the maximum value of z is determined by moving the objective function up along the ...
