Question 1 (1 point) Which of these situations occurs in p3 but not in R?? parallel lines skew lines coincident lines O intersecting lines Question 2 (1 point) Determine a value of k for which the line 41: x= 3+2s, y = 5-s,z= 7+ 1ls, s e R is parallel to the line L2: x = 8+21, y=2-1,z=KIER 3 -2+ O 7+ 21 O 8+ 11 Question 3 (1 point) At what point does the line L: r = (-2,3,1) +s(2,3,-1).s e R intersect the y-axis? O (-23,1) O (29-1) O (0,0,0) (0, 6, 0)
