If a point ( , ) of 3 x+y=0 and (3,4) lie on the opposite sides of 3 x-4 y-8=0 then which of the following is correct?

Options

  1. A15 -8>0
  2. B(- , )
  3. C15 -8=0
  4. D=0

Correct answer

A. 15 -8>0

Step-by-step solution

Given line 3 x + y =0 with ( , ) and line 3 x-4 y-8=0 Satisty (3,4) in the eq 3 x-4 y-8=0 aligned & L ₂=A_ - ( ) _ - ( ) r & 9-16-8 & -7-8=-15 0 & 3 x-4(-3 x)-8>0 & 3 x+12 x>8 & 15 x>8 aligned Satisty x = Then, 15 >8 15 -8>0 .
