The joint equation of the lines passing through the origin and trisecting the first quadrant is ________

Options

  1. A3 x 2 - 4 x y + 3 y 2 = 0
  2. Bx 2 + 3 x y - y 2 = 0
  3. C3 x 2 - y 2 = 0
  4. Dx 2 - 3 x y - y 2 = 0

Correct answer

A. 3 x 2 - 4 x y + 3 y 2 = 0

Step-by-step solution

Hence, slopes of lines are m 1 = 1 3 and m 2 = 3 Pair of lines y - 3 x y - 3 x = 0 x 2 - 4 3 3 x y + y 2 = 0 3 x 2 - 4 x y + 3 y 2 = 0
