![**Problem Statement:**
Find a basis for the null space of the matrix \( A = \begin{bmatrix} 1 & 0 & 1 \\ 0 & 0 & 0 \\ 9 & 0 & 9 \end{bmatrix} \).
**Explanation:**
This problem requires identifying the null space of matrix \( A \), which consists of all vectors \( x \) such that \( A \cdot x = 0 \). A basis for this null space is a set of linearly independent vectors that span this space.
The matrix \( A \) has three rows and three columns and notably includes a row of zeros, which is indicative of dependent equations in a system or automatically extends the null space. Solving this would typically involve setting up and solving the system of linear equations represented by the matrix equation \( A \cdot x = 0 \).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fffc06da2-7bd8-42a3-b8a1-3f8b831a8034%2F51eced3b-6283-4bdd-b8be-f8a3209331a0%2F3stllbx_processed.png&w=3840&q=75)
