Geometrically solve the following LP(Linear Programming):
min x1- 2x2
s.t. x1 - x2 >= -4
-3x1 - 2x2 >= -18
-3x1 + x2 >= -9
x1, x2 >= 0

Again geometrically solve for each of the LPs with the same feasible region as above but with respective objective functions -x1+2x2, and -3x1- x2, and 3x1+x2, and 3x1-3x2. (Five different LPs should be solved, but you can render a single plotting of the feasible region.)
