(A) (3, 0)

(B) (1, 0)

(C) (0.5, 0.5)

 (D) (0.5, 0)

^{Answer D}

Explanation.

origin is at (0,0), putting it  in eq X+7y-2 is  -ve.

Apply option A.   in X+7Y-2   we get  3-2, that is +ve.

similarly option B.  –.ve

option C  (.5+3.5-2)= +ve

Option D (.5-2) is –ve.

Option B and D has the same side as origin.
