Calculate the co-ordinates of the point P which divides the line segment joining: (i) A (1, 3) and B (5, 9) in the ratio 1: 2. (ii) A (-4, 6) and B (3, -5) in the ratio 3: 2. Solution: Question 2. In what ratio is the line joining (2, -3) and (5, 6) divided by the x-axis. Solution: Let the line joining points A (2, -3) and B (5, 6) be divided by point P (x, 0) in the ratio k: 1. Thus, the required ratio is 1: 2. Question 3. In what ratio is the line joining (2, -4) and (-3, 6) divided by the y-axis. Solution: Let the line joining points A (2, -4) and B (-3, 6) be divided by point P (0, y) in the ratio k: 1. Thus, the require...
