સમતલો $\vec r \cdot (3\hat i - \hat j + \hat k) = 1$ અને $\vec r \cdot (\hat i + 4\hat j - 2\hat k) = 2$ ની છેદરેખાનું સમીકરણ શોધો.

• A
  $\frac{x - 4/7}{-2} = \frac{y}{7} = \frac{z - 5/7}{13}$
• B
  $\frac{x - 4/7}{2} = \frac{y}{-7} = \frac{z + 5/7}{13}$
• C
  $\frac{x - 6/13}{2} = \frac{y - 5/13}{-7} = \frac{z}{-13}$
• D
  $\frac{x - 6/13}{2} = \frac{y - 5/13}{7} = \frac{z}{-13}$
