8. Determine the point of intersection of the three planes 1 1: x+ 3y-z+9=0 2: X-y+2-11 =0 73: [x, y, z] = [1, 0, 1] + s[2, 1, -1] + #[4, 0, -1]. a. (1, -4, 3) C. (5, -4, 2) b. (5, 0, -5) d. (5, 11, -12) Communication [13 marks] ing the intersection of True/False Indicate whether the statement is true or false. 9. A normal vector to a line is parallel to that line. 10. There is no symmetric form for the equation of a plane. 121 11. A plane written in scalar form can be written in vector form. 12. In three-space there are two possibilities for the intersection of two lines. 13. A line will never intersect with a plane. on the plane It. y.215 Matching Match the equation of each plane to its scalar form.
