Using section formula, show that the points A (2, –3, 4), B (–1, 2, 1) and C (0, , 2) are collinear.

The given points are A (2, –3, 4), B (–1, 2, 1), and C (0, ,2).

Let P be a point that divides AB in the ratio k: 1

Hence, by section formula, the coordinates of P are given by

{(-1 × k + 2) ÷ (k + 1), (2 × k - 3) ÷ (k + 1), (1 × k + 4) ÷ (k + 1)}

Now, we find the value of k at which point P coincides with point C.

By taking (-k + 2) ÷ (k + 1) = 0, we obtain k = 2 For k = 2, the coordinates of point P are (0, , 2)

i.e., C (0, , 2) is a point that divides AB externally in the ratio 2: 1 and is the same as point P. Hence, points A, B, and C are collinear.
