  1. A \(4\)
  2. B \(5\)
  3. C \(6\)
  4. D \(7\)
Verified Solution

Answer & Solution

Correct Answer

(D) \(7\)

Step-by-step Solution

Detailed explanation

\(\overrightarrow{\mathrm{QR}}: \frac{x-3}{1}=\frac{y+4}{-1}=\frac{z+5}{-6}=r\) \(\Rightarrow(x, y, z) \equiv(r+3,-r-4,-6 r-5)\) Now, satisfying it in the given plane. \(2(r+3)+(-r-4)+(-6 r-5)=7\) We get \(r=-2\) so, required point of intersection is \(\mathrm{T}(1,-2,7) .\)…
