Question

If the lines x squared plus 2 x y minus 35 y squared minus 4 x plus 44 y minus 12 equals 0 and 5 x plus lambda y minus 8 equals 0 are concurrent then λ

  1. 0
  2. 1
  3. -1
  4. 2

hintHint:

The line should satisfy the point of intersection of the pair of straight lines.

The correct answer is: 2


    Given That:
    If the lines x squared plus 2 x y minus 35 y squared minus 4 x plus 44 y minus 12 equals 0 and 5 x plus lambda y minus 8 equals 0 are concurrent then λ
    >>> The point of intersection of pair of straight lines becomes:
    p(x, y) = left parenthesis fraction numerator h f minus b g over denominator a b minus h squared end fraction comma fraction numerator h g minus a f over denominator a b minus h 2 end fraction right parenthesis
    >>> Therefore, the point of intersection becomes:
    p(x, y) = (4 over 3,2 over 3)
    >>> Therefore, it should satisfy the given line :
    5 x plus lambda y minus 8 equals 0
    5 left parenthesis 4 over 3 right parenthesis plus lambda left parenthesis 2 over 3 right parenthesis minus 8 space equals space 0
    lambda = 2.
    >>> Therefore, the value of lambda is 2.

    >>> The value of lambda is 2.
