Answer:

  • E'(-2, 2)
  • F'(0, 0)
  • G'(-2, -2)

Explanation:

You want the coordinates of the vertices of ∆E'F'G' after ∆EFG has been dilated with a scale factor of 1/4.

Dilation

Dilation about the origin multiplies each preimage coordinate by the scale factor.

E' = (1/4)E = (1/4)(-8, 8) = (-2, 2)

F' = (1/4)F = (1/4)(0, 0) = (0, 0)

G' = (1/4)G = (1/4)(-8, -8) = (-2, -2)

The coordinates after dilation are E'(-2, 2), F'(0, 0), G'(-2, -2).
