What does linearly dependent mean? My teacher and textbook do not teach nor define it. What is it? An example of one is found below, however, how does one solve it?

17.Determine if the following vectors are linearly dependent.

u = [4, 1, 0], v = [-8, 5, 2,], w = [0, 7, 2].

How does one solve this and prove that it is linearly dependent?
