Question

A line segment has endpoints (1, 1)
and (4, 4)
. Demonstrating the properties of reflections across the y
-axis, what are the reflected endpoints?(1 point)
Responses

(−1, 1)
and (4, 4)

left parenthesis negative 1 comma 1 right parenthesis and left parenthesis 4 comma 4 right parenthesis

(−1, 1)
and (−4, 4)

left parenthesis negative 1 comma 1 right parenthesis and left parenthesis negative 4 comma 4 right parenthesis

(1, −1)
and (4, −4)

left parenthesis 1 comma negative 1 right parenthesis and left parenthesis 4 comma negative 4 right parenthesis

(−1, −1)
and (−4, −4)

Answer 1

Reflection across the y-axis maps (x,y) → (−x,y). So (1,1) → (−1,1) and (4,4) → (−4,4). The correct choice is (−1, 1) and (−4, 4).
