JEE Mains · Maths · STD 11 - 9. straight line

यदि सरल रेखा \(2 x-3 y+17=0\), बिन्दुओं \((7,17)\) तथा \((15, \beta)\) से होकर जाने वाली रेखा के लंबवत् है, तो \(\beta\) बराबर है

  1. A \(\frac{35}{3}\)
  2. B \(-5\)
  3. C \(-\frac{35}{3}\)
  4. D \(5\)
Verified Solution

Answer & Solution

Correct Answer

(D) \(5\)

Step-by-step Solution

Detailed explanation

Line perpendicular to \(2x-3y+5=0\) is \(3x+2y+c=0\) Which is satisified by point \((7,17)\) \( \Rightarrow 3\left( 7 \right) + 2\left( {17} \right) + c = 0\) \( \Rightarrow c = - 55\) \( \Rightarrow \) equation of line is \(3x+2y-55=0\)…
