यदि एक समांतर चतुर्भु ज \(ABDC\) के बिन्दुओं \(A , B\) तथा \(C\) के निर्देशांक क्रमशः \((1,2),(3,4)\) तथा \((2,5)\) हैं, तो विकर्ण \(AD\) का समीकरण है 

  1. A \(5x - 3y +1 = 0\)
  2. B \(5x + 3y -11 = 0\)
  3. C \(3x - 5y + 7 = 0\)
  4. D \(3x + 5y -13 = 0\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(5x - 3y +1 = 0\)

Step-by-step Solution

Detailed explanation

\(E\) is \(\left( {\frac{5}{2},\frac{9}{2}} \right)\) Slope of \(AD = \frac{5}{3}\) Equation of \(AD\) is \(y - 2 = \frac{5}{3}\left( {x - 1} \right)\) \( \Rightarrow 5x - 3y + 1 = 0\)
