Text Solution

AI Generated Solution

To show that the points \( A(2, 3, 4) \), \( B(-1, -2, 1) \), and \( C(5, 8, 7) \) are collinear, we can use the concept of vectors. If the vectors formed by these points are scalar multiples of each other, then the points are collinear. ### Step 1: Define the points Let: - \( A = (2, 3, 4) \) - \( B = (-1, -2, 1) \) - \( C = (5, 8, 7) \) ...
