Verified Solution

Answer & Solution

Correct Answer

(C) \(-3: 7\)

Step-by-step Solution

Detailed explanation

Let \(X O Z\)-plane divides the joining the point \((2,3,1)\) and \((6,7,1)\) into \(m: n\), then the co-ordinate of \(X O Z\)-plane is \(\left(\frac{m x_2+n x_1}{m+n}, \frac{m y_2+n y_1}{m+n}, \frac{m z_2+n z_1}{m+n}\right)\)…
