if you mean k as a constant then k ≠ 0 because 0 is not a constant, there would be no relationship if k = 0
The value of k cannot be equal to 0 because it represents a constant that defines relationships in equations. If k is 0, it nullifies those relationships, leading to meaningless or unchanging results. In contexts such as proportionality or physical laws, a k of 0 indicates the absence of interaction or change.
