No 1 masih bingung.. soalnya kayaknya mirip.. Find the equation of the line which passes through the point (1, 2, 3) and is parallel to the vector 3i + 2j - 2k. Answer: It is given that the line passes through the point A (1, 2, 3). Therefore, the position vector through A is a = i + 2j + 3k b = 3i + 2j - 2k It is known that the line which passes through point A and parallel to b is given by r = a + λb, where λ is a constant. => r = (i + 2j + 3k) + λ (3i + 2j - 2k) This is the required equation of the line.
