The, required plane should contain the lines, and

So, it is clear from the given equation of lines, that both the lines are passing through a point and one of the line is parallel to and the other one is parallel to .

So, the equation of the vector normal to the plane is given as,

So, in scalar product form the vector equation of the plane is given as,

.

Hence, the equation of the plane containing the lines and is given as, or,
