Question

Assertion :If the lines $\frac{x - x_{1}}{a_{1}} = \frac{y - y_{1}}{b_{1}} = \frac{z - z_{1}}{c_{1}}$ and $\frac{x - x_{2}}{a_{2}} = \frac{y - y_{2}}{b_{2}} = \frac{z - z_{2}}{c_{2}}$ are coplanar then $∣ ∣ ∣ ∣ \begin{matrix} x_{1} & y_{1} & z_{1} a_{1} & b_{1} & c_{1} a_{2} & b_{2} & c_{2} \end{matrix} ∣ ∣ ∣ ∣ = ∣ ∣ ∣ ∣ \begin{matrix} x_{2} & y_{2} & z_{2} a_{1} & b_{1} & c_{1} a_{2} & b_{1} & c_{1} \end{matrix} ∣ ∣ ∣ ∣$
