To perform the translation \( T_{-3, -5} \) on the triangle \( ABC \), we subtract 3 from the x-coordinates and 5 from the y-coordinates of each vertex.

Given the vertices of triangle \( ABC \):

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

We will apply the translation:

  1. For vertex \( A(4, -2) \): \[ A' = (4 - 3, -2 - 5) = (1, -7) \]

  2. For vertex \( B(-1, -3) \): \[ B' = (-1 - 3, -3 - 5) = (-4, -8) \]

  3. For vertex \( C(2, 1) \): \[ C' = (2 - 3, 1 - 5) = (-1, -4) \]

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

  • \( A'(1, -7) \)
  • \( B'(-4, -8) \)
  • \( C'(-1, -4) \)

So, the complete answer is:

  • \( A' = (1, -7) \)
  • \( B' = (-4, -8) \)
  • \( C' = (-1, -4) \)
