your ray is defined by (in 3D) :

r = L + t (V - L)

and your plane as :

p = P0 + u(P1 - P0) + v(P2 - P0)

with P0, P1 and P2 the three points that define the plane (not on one line !).

To find where the ray "cuts" the plane :

L + t (V - L) = P0 + u(P1 - P0) + v(P2 - P0)

This can be easily solved for unknowns t, u and v ...
