To find the vertices of triangle \( A'B'C' \) after the translation \( T_{(-4,5)}( \triangle ABC) \), we will apply the translation to each vertex of triangle \( ABC \).

The translation \( T_{(-4,5)} \) means that we will subtract 4 from the x-coordinate and add 5 to the y-coordinate of each vertex.

Here are the vertices of triangle \( ABC \):

  • \( A(2, -1) \)
  • \( B(-2, -3) \)
  • \( C(4, 3) \)

Now we will translate each vertex:

  1. For Vertex A: \[ A' = (2 - 4, -1 + 5) = (-2, 4) \]

  2. For Vertex B: \[ B' = (-2 - 4, -3 + 5) = (-6, 2) \]

  3. For Vertex C: \[ C' = (4 - 4, 3 + 5) = (0, 8) \]

Now we can summarize the vertices of triangle \( A'B'C' \):

  • \( A'(-2, 4) \)
  • \( B'(-6, 2) \)
  • \( C'(0, 8) \)

Therefore, the vertices of triangle \( A'B'C' \) are:

  • \( A'(-2, 4) \)
  • \( B'(-6, 2) \)
  • \( C'(0, 8) \)

In conclusion:

  • A' = (-2, 4)
  • B' = (-6, 2)
  • C' = (0, 8)
