URGENT!!! please help me with all of these questions, thanks

22. Find the intercepts of the plane 2x+ y 32- 12 - . [2] 23. The point (1, k, 4) lies on the plane [x,y, z] = [1, 2, 0] + s[3, 0, 1] + t[2, 1, 1]. Find the value ofk. [2] 24. By analysing the normals, determine if the two planes intersect in a line, are parallel and distinct, or are coincident. [2] :1: :r+ 2y+ 32 3 = I] In: 2x-y+z7=D 25.
