Question

the effect of transformations. 83c19. point c(12, 5) was reflected to c(-12, 5)what was the line of reflection?g. (-x, y)h. (y, -x)

Explanation:

Step1: Compare original and reflected points

Original point: $C(12, 5)$; Reflected point: $C'(-12, 5)$

Step2: Identify coordinate change

The $x$-coordinate is negated ($12 \to -12$), while the $y$-coordinate stays the same ($5 \to 5$).

Step3: Match to reflection rule

A reflection that negates the $x$-coordinate and preserves the $y$-coordinate is over the $y$-axis (the line $x=0$).

Answer:

The line of reflection is the $y$-axis (or the line $x=0$)
