Short answer
If it holds that for a nonempty collection of vectors X := \{x_1,\ldots, x_K\} \subset \mathbb{R}^N \sum_{k=1}^K \alpha_k x_k = 0 \; \Rightarrow \; \alpha_1 = \cdots = \alpha_K = 0, they are called [missing word 1] [missing word 2]. Write the first missing word

Step-by-Step Analysis
The problem describes a condition on a set of vectors X = {x1, ..., xK} in R^N: if a linear combination sum_{k=1}^K alpha_k x_k = 0 implies alpha_1 = ... = alpha_K = 0, then the vectors have a specific property.
