**Question 1:** Construct a nonzero \(2 \times 2\) matrix \(A\) such that the solution set of the equation \(Ax = 0\) is the line in \(\mathbb{R}^2\) through (6,1) and the origin. Then, find a vector \(b\) in \(\mathbb{R}^2\) such that the solution set of \(Ax = b\) is not a line in \(\mathbb{R}^2\) parallel to the solution set of \(Ax = 0\). Why does this not contradict the theorem that states that if the equation \(Ax = b\) is consistent for some given \(b\) and \(p\) is a solution, then the solution set of \(Ax = b\) is the set of all vectors of the form \(w = p + v_h\), where \(v_h\) is any solution of the homogeneous equation \(Ax = 0\)? --- **Question 2:** Construct a nonzero \(2 \times 2\) matrix \(A\) such that the solution set of the equation \(Ax = 0\) is the line in \(\mathbb{R}^2\) through (6,1) and the origin. Choose the correct answer below: - \( \text{A.} \quad \begin{bmatrix} 1 & 6 \\ 1 & 6 \end{bmatrix} \) - \( \text{B.} \quad \begin{bmatrix} 1 & 1 \\ 6 & 6 \end{bmatrix} \) - \( \text{C.} \quad \begin{bmatrix} 1 & -6 \\ 1 & -6 \end{bmatrix} \) - \( \text{D.} \quad \begin{bmatrix} 1 & 1 \\ -6 & -6 \end{bmatrix} \)
