Answer both pls

4. Determine the points of intersection between the line L: P = (1, D, 2) + t(3, 1, 0), t E R and the plane 1r: 3x y + 22 = 4 if any exist. Consider the following planes: 7r] :2;I'+4y : = W237:i'y:7 7T3Z41' + 8;} 1L = 1 a) Are any of the planes parallel? How do you know? b) Determine the solution(s) to the system of equations AND describe the way in which the planes interact. c) Determine the intersection of H1 and m: x 2y + z = 1 if one exists. d) Determine the distance between 1:3 and 7:5: 83: + 16y 222 = 5
