Section formula,We know that the coordinates of the point R, which divide the line segment joining two points, P (x1, y1, z1) and Q (x2, y2, z2), externally in the ratio m: n, are given byUpon comparing, we havex1 = -2, y1 = 3, z1 = 5;x2 = 1, y2 = -4, z2 = 6 andm = 2, n = 3So, the coordinates of the point which divide the line segment joining the points P (– 2, 3, 5) and Q (1, – 4, 6) in the ratio 2: 3 externally are given by∴ The coordinates of the point which divides the line segment joining the points (-2, 3, 5) and (1, -4, 6) are (-8, 17, 3).2. Given that P (3, 2, – 4), Q (5, 4, – 6) and R (9, 8, –10) are collinear. Find the ratio in which Q divides PR.Solution:Let us consider Q divides PR in the ratio k: 1.By using the section formula,We know that the coordinates of the point R, which divides the line segment joining two points, P (x1, y1, z1) and Q (x2, y2, z2), internally in the ratio m : n, are given byUpon comparing, we havex1 = 3, y1 = 2, z1 = -4;x2 = 9, y2 = 8, z2 = -10 andm = k, n = 1So, we have9k + 3 = 5 (k+1)9k + 3 = 5k + 59k – 5k = 5 – 34k = 2k = 2/4= ½Hence, the ratio in which Q divides PR is 1: 2.3. Find the ratio in which the YZ-plane divides the line segment formed by joining the points (–2, 4, 7) and (3, –5, 8).Solution:Let the line segment formed by joining the points P (-2, 4, 7) and Q (3, -5, 8) be PQ.We know that any point on the YZ-plane is of the form (0, y, z).So now, let R (0, y, z) divide the line segment PQ in the ratio k: 1.Then,Upon comparing, we havex1 = -2, y1 = 4, z1 = 7x2 = 3, y2 = -5, z2 = 8 andm = k, n = 1By
