The left side of the equation HAS TO BE GREATER THAN 3
So we take each ordered pair (x,y), plug it into the expression of left side of inequality and see which one is GREATER THAN 3. That's our answer.
A:
0.5x - 2y
0.5(-2) -2(0.5) = -2
NO
B:
0.5x - 2y
0.5(2) -2(1) = -1
NO
C:
0.5x -2y
0.5(2) -2(-1) = 3
NO
D:
0.5x -2y
0.5(-2) -2(-0.5) = 0
NO
None of them are solutions. C would have been a solution if the inequality had an "EQUAL SIGN" -- but it doesn't. Maybe the question is wrong, but if the question is right, then there is no correct answer.
