Find the line through the intersection of 2x + y - 5 = 0 and x + 3y - 5 = 0 that also passes through (0, 0).

  1. 2x - y = 0
  2. x - 2y - 1 = 0
  3. x + 2y = 0
  4. x - 2y = 0
Answer

D) x - 2y = 0

The lines meet at (2, 1). The line through (2, 1) and (0, 0) is x - 2y = 0 (you can also use L1 + kL2 = 0 and find k from the point). SLO M-09-B-11 · Understanding
