Question

what is the image point of (1, -7) after the transformation $r_{90^{circ}} \circ r_{x-axis}$?
answer attempt 1 out of 2
(\square, \square)

Explanation:

Step1: Aplicar \( r_{x\text{-axis}} \)

La reflexión sobre el eje \( x \) transforma un punto \( (x, y) \) en \( (x, -y) \). Para \( (1, -7) \):
\( r_{x\text{-axis}}(1, -7) = (1, -(-7)) = (1, 7) \)

Step2: Aplicar \( R_{90^\circ} \)

La rotación de \( 90^\circ \) en sentido antihorario transforma \( (x, y) \) en \( (-y, x) \). Aplicamos a \( (1, 7) \):
\( R_{90^\circ}(1, 7) = (-7, 1) \)

Answer:

\((-7, 1)\)
