if rectangle abdc is translated horizontoally -1 and vertically +3, which of the following correctly depcits rectangle A' B' D' C?

A = (-5,4) B = (-1,4) C = (-5,1) D = (-1,1)

To determine the coordinates of the translated rectangle A'B'C'D', we need to apply the horizontal and vertical translations to each vertex of rectangle ABCD.

The translations given are:

  • Horizontal shift: -1 (which means we move left by 1 unit)
  • Vertical shift: +3 (which means we move up by 3 units)

Let's apply these translations to each vertex:

  1. Vertex A: \( A = (-5, 4) \)

    • New x-coordinate: \( -5 - 1 = -6 \)
    • New y-coordinate: \( 4 + 3 = 7 \)
    • New position: \( A' = (-6, 7) \)
  2. Vertex B: \( B = (-1, 4) \)

    • New x-coordinate: \( -1 - 1 = -2 \)
    • New y-coordinate: \( 4 + 3 = 7 \)
    • New position: \( B' = (-2, 7) \)
  3. Vertex C: \( C = (-5, 1) \)

    • New x-coordinate: \( -5 - 1 = -6 \)
    • New y-coordinate: \( 1 + 3 = 4 \)
    • New position: \( C' = (-6, 4) \)
  4. Vertex D: \( D = (-1, 1) \)

    • New x-coordinate: \( -1 - 1 = -2 \)
    • New y-coordinate: \( 1 + 3 = 4 \)
    • New position: \( D' = (-2, 4) \)

Now we have the new coordinates:

  • \( A' = (-6, 7) \)
  • \( B' = (-2, 7) \)
  • \( C' = (-6, 4) \)
  • \( D' = (-2, 4) \)

Thus, the translated rectangle A'B'C'D' has the following vertices:

  • A' = (-6, 7),
  • B' = (-2, 7),
  • D' = (-2, 4),
  • C' = (-6, 4).

You would now look for a depiction of these coordinates on a graph or within a multiple-choice format to find the correct representation of rectangle A'B'D'C'.
