A graphic designer wants to translate rectangle DEFG using T–1, 2(x, y). The pre-image has coordinates D(–1, 3),

E(4, 3), F(4, 1), and G(–1, 1). What is the image of DEFG?

On a coordinate plane, a rectangle has points D prime (negative 1, 3), E prime (4, 3), F prime (4, 1), G prime (negative 1, 1).

On a coordinate plane, a rectangle has points D prime (negative 2, 5), E prime (3, 5), F prime (3, 3), G prime (negative 2, 3).

On a coordinate plane, a rectangle has points D prime (0, 2), E prime (5, 2), F prime (5, 0), G prime (0, 0).

On a coordinate plane, a rectangle has points D prime (negative 1, negative 1), E prime (4, negative 1), F prime (4, negative 3), G prime (negative 1, negative 3).

To find the image of rectangle DEFG when translated using \( T_{-1, 2}(x, y) \), we need to apply the translation transformation to each of the vertices of the rectangle.

The translation \( T_{-1, 2}(x, y) \) shifts each point \( (x, y) \) to a new location given by:

\[ (x', y') = (x - 1, y + 2) \]

Now, let's apply this translation to each of the points:

  1. For point D(-1, 3): \[ D' = (-1 - 1, 3 + 2) = (-2, 5) \]

  2. For point E(4, 3): \[ E' = (4 - 1, 3 + 2) = (3, 5) \]

  3. For point F(4, 1): \[ F' = (4 - 1, 1 + 2) = (3, 3) \]

  4. For point G(-1, 1): \[ G' = (-1 - 1, 1 + 2) = (-2, 3) \]

After applying the translation, the new coordinates are:

  • D'(-2, 5)
  • E'(3, 5)
  • F'(3, 3)
  • G'(-2, 3)

Thus, the image of rectangle DEFG after the translation is:

  • D'(-2, 5)
  • E'(3, 5)
  • F'(3, 3)
  • G'(-2, 3)

The coordinates that match this translation correspond to the option: On a coordinate plane, a rectangle has points D prime (negative 2, 5), E prime (3, 5), F prime (3, 3), G prime (negative 2, 3).
