### Problem Statement:

Given the vectors:

\[
\mathbf{v}_1 = \begin{pmatrix} 3 \\ 1 \\ 5 \end{pmatrix}; \quad \mathbf{v}_2 = \begin{pmatrix} -2 \\ -5 \\ 1 \end{pmatrix}; \quad \mathbf{y} = \begin{pmatrix} 4k \\ -6 \\ -2k \end{pmatrix}
\]

The question asks: For what value(s) of \( k \) is \(\mathbf{y}\) in the plane spanned by \(\mathbf{v}_1\) and \(\mathbf{v}_2\)?

Instructions:
- Show all your work, do not skip steps.
- Displaying only the final answer is not enough to get credit.

This problem requires you to determine the value(s) of \( k \) such that the vector \(\mathbf{y}\) can be expressed as a linear combination of the vectors \(\mathbf{v}_1\) and \(\mathbf{v}_2\).
