2. option 2 is correct.

   step-by-step explanation:

   we are given two inequality equation

   x+y> 5 and -3x+2y< -2

   first we draw the graph of both function using t-table method

   equation: x+y> 5

   for x=0, y=5

   for x=-5, y=0

   table:

   x   :   0     5

   y   :   5     0

   test point (0,0) , 0> 5

   false

   equation: -3x+2y< -2

   for x=0, y=-1

   for x=2, y=4

   table:

   x   :   0     2

   y   : -1       4

   test point (0,0) , 0< -2

   true

   now we draw the graph. see the attachment for graph.

   common region would be solution set.

   option 2 is correct.
