For the three points \(A(2,0), B(0,2)\) and \(P(1,1)\), suppose \(d\) is the algebraic sum of the distances of \(A\) and \(B\) from a line that passes through \(P\). Then, which of the following is correct?

  1. A \(d>0\) for all lines
  2. B \(d=0\) for at least one line
  3. C \(d=0\) for all lines
  4. D \(d>0\) at least for one line
Verified Solution

Answer & Solution

Correct Answer

(C) \(d=0\) for all lines

Step-by-step Solution

Detailed explanation

Let the variable line be \(a x+b y+c=0\) The line passes through \((1,1)\), then \[ a+b+c=0...(i) \] \(d=\) algebraic sum of distance from \(A\) and \(B\) to the line…
