1. triangle abc is transformed to triangle def as shown below. write a rule that describes this transformation.

a. trace the axis that is the line of reflection.
b. over which axis is the figure reflected? (circle one below)
x - axis y - axis
c. what are the coordinates for point a? (__, __)
d. what are the coordinates for point d? (__, __)
e. write the rule that describes this transformation.
(x, y)→(__, __)

Explanation:

Step1: Encontrar coordenadas de A

A está en (-3, 2)

Step2: Encontrar coordenadas de D

D está en (-3, -2)

Step3: Determinar eje de reflexión

Cambio en coordenada y: reflexión sobre eje x

Step4: Regla de transformación

(x,y) → (x, -y)

Answer:

a. Trazar el eje x.
b. x-axis
c. (-3, 2)
d. (-3, -2)
e. (x, -y)
