Question

Suppose that L1 is the line through point (1, 2, 3) with direction vector [2 ,- 3 ,0]t.

And suppose that L2 is the line given by the intersection of the two planes

x + y - z = 1 and 2x - y + z = 2

1.1 Show that L1 and L2 do not intersect.

1.2 Explain why L1 and L2 are not parallel.

1.3 Determine the shortest distance between any two points, P1 and P2, where P1 lies on L1 and P2 lies on L2.
