Sorry about another maths help thread, but I'm brain dead at the moment.

Question: we have to find an equation for the pla ne that contains the line
x = 1+t , y = 3*t and z= 2*t
and is parallel to the line of intersection of the planes
-x + 2*y +z = 0 and x + z + 1 = 0

So basically theres 3 parts to this qu. Really struggling, any help appreciated. Thanks
