12th grade calculus. Need a detailed process thank you

121) Find the x-, y-, zintercepts of the plane [x, y, z] = [1, 2, 0] + s [3, O, 1] + t [2, 1, 1]. 1b) Find the k such that the line through the points A (8, -5, 2) and B (k, 4k1, 2k+1) does not intersect the plane [x, y, z] = [1, 2, O] + s[3, 0, 1] + t[2, 1, 1]
