Answer:

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

Step-by-step 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)
