pls help, I can't figure out what to do, I have looked at 2 LA books and neither mention how to work this out. Any help?

------------------------------------------------------

Suppose L1 is the line in R^3 that passes through the points (2, 0, −1) and (3, 1, 1) , and L2 is the line in R^3 defined

by

(x, y, z) = (2, 1, 2) + t (1, 0, 1) , t ∈ R.

Suppose V is the plane in R^3 defined by

−x − y − 2z = 2

A) Determine an equation for the plane W that contains the line L1 and is perpendicular to the plane V?

B) Does the line L2 intersect the plane V? If so, give the point(s) of intersection. If not, give a reason why not?
