Web16. sep 2024 · Theorem 5.4. 2: Reflection. Let Q m: R 2 → R 2 be a linear transformation given by reflecting vectors over the line y → = m x →. Then the matrix of Q m is given by. 1 1 + m 2 [ 1 − m 2 2 m 2 m m 2 − 1] Consider the following example. Webthe reflection in the y-axis takes ( x, y, z) → ( − x, y, − z). You can write down the matrix from this fact, and you can also get it using R = 2 P − I, where P is the matrix that projects each point onto the y-axis.
