Straight Lines · Diagonals of a rhombus

Let A(1,2)A(1, 2) and C(−3,−6)C(-3, -6) be two diagonally opposite vertices of a rhombus, whose sides ADAD and BCBC are parallel to the line 7x−y=147x - y = 14. If B(α,β)B(\alpha, \beta) and D(γ,δ)D(\gamma, \delta) are the other two vertices, then ∣α+β+γ+δ∣\lvert\alpha + \beta + \gamma + \delta\rvert is equal to:
  1. (1)9
  2. (2)3
  3. (3)6
  4. (4)1
We corrected a printing error in the original paper
