Can you help me with this question. It is part of Grade 12 - Vectors - Chapter 9 (Relationships between points, lines, and planes)

Can you show the steps as well

Question

1. a. Determine the point of intersection for the lines having equations r = (4, 2, 6) + s(1, 3, 11), SER, and r = (5, -1, 4) + t(2, 0, 9), tER. b. Verify that the intersection point of these two lines is on the plane x - y + z +1 =0
