Find the line through the intersection of x + y - 5 = 0 and 3x - y - 11 = 0 that also passes through (0, 0).

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

D) x - 4y = 0

The lines meet at (4, 1). The line through (4, 1) and (0, 0) is x - 4y = 0 (you can also use L1 + kL2 = 0 and find k from the point). SLO M-09-B-11 · Understanding
