7. Three planes can intersect in a number of different ways. For each of the combinations below, find the single point of intersection if there is one. If there isn't, explain how the planes do intersect. (6 marks) 71 : 3x + 4y+ 22-1 = O a. 72 : -2x + 5y + 3z +7 = 0 13 : 5x + 4y + 22 -3 = 71 : x - 2y+ 32-1 = 0 b. 72 : -3x + 5y + 2z +7 = 0 73 : -x+y+82+5 = 0 8. Give the equations of three planes that meet in three lines. Explain your reasoning and include a LanGraph of your planes that allows you to see the triangular prism created. (4 marks)
