Question
Determine if the Standard Matrix is a projection, reflection, rotation, or none of these.
![Here is the transcription of the matrix for an educational website:
The expression shown is:
\[
\frac{1}{9} \begin{bmatrix} -1 & 4 & 8 \\ 4 & -7 & 4 \\ 8 & 4 & -1 \end{bmatrix}
\]
This is a 3x3 matrix with elements arranged in three rows and three columns. Each element in the matrix is denoted by its position:
- First row: \(-1, 4, 8\)
- Second row: \(4, -7, 4\)
- Third row: \(8, 4, -1\)
The entire matrix is multiplied by the scalar \(\frac{1}{9}\), which means each element in the matrix should be divided by 9 when calculating with it. This scalar multiplication affects every element of the matrix uniformly.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa824ef54-0ee2-4591-9058-ff8a94975446%2F9ba43fb6-3d6a-41aa-a7f2-d9e421372bc9%2Fyqez1u7_processed.jpeg&w=3840&q=75)
