Question

HELP DUE IN 15 MINUTES!!!! REFLECTIONS!

Answer 1

D(-1,-1), E(-8,-4), F(-8,-8)

Answer 2

• D'(-1, 1)
• E'(-4, 8)
• F'(-8, 8)

Explanation:

The coordinates of the given vertices are ...

• D(1, 1)
• E(4, 8)
• F(8, 8)

Reflection across the y-axis changes the sign of the x-coordinate:

(x, y) ⇒ (-x, y) . . . . . . reflection across the y-axis

This means the reflected figure has coordinates ...

D(1, 1) ⇒ D'(-1, 1)

E(4, 8) ⇒ E'(-4, 8)

F(8, 8) ⇒ F'(-8, 8)
