Show that the lines are coplanar. Also, find the equation of the plane containing these lines.

Given: Lines are:




To Show: Lines are coplanar


Proof:



Firstly, we find


Here,


So,





Now, we know that


The given are coplanar if and only if is perpendicular to


i.e.


Here,







Now, we have to find




We know that, in dot product



= -10 +10


= 0


∴ Given lines are co planar





∴ Equation of plane is
