4. A line can either lie on a plane, lie parallel to it or intersect it. (6 marks) a. Determine, if there is one, the point of intersection between the line and plane given: L1 : X-7 - y-9 2 4 3 712 : [, y, z] = [5, 4, -1] + s [2, 3, 1] + t [4, -1, -2] b. Determine the angle between the line and the plane. c. Give the equation of a plane and three lines, one of which is parallel to the plane, one of which lies on the plane, and one of which intersects the plane.
