MCV4U UnitTest6: Equations of Lines and Planes 12K 12A 12C 12T Note: communication marks will be given for clear and well organized solutions. 1) [2K] Determine the distance between the point P(2, -5) and the line L: T = (-4, 0) + t(2, 3), tER. 2) [2K] Determine whether r = -1, y = 3 and z = 5 is a solution to the system: a) 4x - 2y + z = -5 b) x + 3y - 2z =7 3) [6C] Describe 4 of the 6 possible ways in which 3 planes can interact. Draw diagrams to help you. How many solutions does each case give
