Find the line through the intersection of x - y + 4 = 0 and x + 3y - 8 = 0 that also passes through (1, 1).

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

A) x + y - 2 = 0

The lines meet at (-1, 3). The line through (-1, 3) and (1, 1) is x + y - 2 = 0 (you can also use L1 + kL2 = 0 and find k from the point). SLO M-09-B-11 · Understanding
