If its diagonals intersect at (−1,−2)(-1, -2)(−1,−2), then which one of the following is a vertex of this rhombus?A(13,−83)\left( {{{ 1} \over 3}, - {8 \over 3}} \right)(31,−38)B(−103,−73)\left( - {{{ 10} \over 3}, - {7 \over 3}} \right)(−310,−37)C(−3,−9)\left( { - 3, - 9} \right)(−3,−9)D(−3,−8)\left( { - 3, - 8} \right)(−3,−8)Check answerSkip
