The solution (2,1) is feasible for which of the following inequalities?
-2x - 4y > -6
2x - 4y < 0
-2x + 4y greater than or equal to sign 0
2x + 4y less than or equal to 6
Just input, (2,1) is for (x,y), so for the first one -4 - 4 = -8, False, the second, 2 - 4 = -2, false, the third, -2 + 4 = 2, true, and the fourth, 2 + 4 = 6, true. Both 3 and 4
