Two sides of a rhombus are along the lines, x−y+1=0x - y + 1 = 0x−y+1=0 and 7x−y−5=07x - y - 5 = 07x−y−5=0. If its diagonals intersect at (−1,−2)(-1, -2)(−1,−2), then which one of the following is a vertex of this rhombus?
  1. A
    (13,−83)\left( {{{ 1} \over 3}, - {8 \over 3}} \right)(31​,−38​)
  2. B
    (−103,−73)\left( - {{{ 10} \over 3}, - {7 \over 3}} \right)(−310​,−37​)
  3. C
    (−3,−9)\left( { - 3, - 9} \right)(−3,−9)
