Question
**Triangle with Linear Transformation**

Let \( P \) denote a triangle with the following vertices:

\[ 
A = [6, 1] 
\]
\[ 
B = [7, 4] 
\]
\[ 
C = [10, 2] 
\]

Give an example of a matrix \( M \) such that the linear transformation \( T : \mathbb{R}^2 \rightarrow \mathbb{R}^2 \) given by \( T(\mathbf{v}) = M \mathbf{v} \) satisfies the following conditions:

- \( T \left( \begin{bmatrix} 1 \\ 0 \end{bmatrix} \right) = \begin{bmatrix} 2 \\ 6 \end{bmatrix} \)
- \( T \) transforms the triangle \( P \) into a triangle of area 8.

**Graph Description:**

The graph to the right shows triangle \( P \) on a coordinate plane. Points \( A \), \( B \), and \( C \) correspond to the vertices specified above. The triangle is shaded in orange and has edges connected by bold red lines. Each vertex is labeled accordingly, showing the location of points \( A(6,1) \), \( B(7,4) \), and \( C(10,2) \) on the graph. The background grid aids in visualizing the position and shape of the triangle within the boundary of the axes ranging from 4 to 12 on the x-axis and 0 to 6 on the y-axis.
