MCV 4U - Units 8 and 9 Assignment Page 2 of 2 Part C: Thinking (12 marks) 10. A plane is perpendicular to both [x, y, z] = [1, -10,8] + s[1,2, -1] and [x, y,z] = [2,5, -5] + t[2,1, -3], and contains the point P(-1,4, -2). Determine if the point A(7,10,16) is also on this plane. [6 marks] 11. The line of intersection between the planes m : x + y + z = 7 and nt2: 2x - 3y - z = -8 crosses the xz - plane at point A, and the yz - plane at point B. What is the length of the line segment (correct to two decimal places) connecting points A and B? [6 marks] Part D: Communication (12 marks) 12. Determine the Cartesian and vector equations of the line shown in the graph to the right. [2 marks] +
