After applying a translation vector to rectangle ABCD, the coordinates of A' are (-6,8). What are the coordinates of B'?

Coordinate A is at (-3,2)
Coordinate B is at (-1,2)

1 answer

To determine the coordinates of point B' after the translation, we first need to analyze the translation vector based on the change from point A to point A'.

  1. Identify the coordinates of point A and A':

    • Point A: (-3, 2)
    • Point A': (-6, 8)
  2. Calculate the translation vector: To find the translation vector, we calculate the change in the x and y coordinates:

    • Change in x: x' - x = -6 - (-3) = -6 + 3 = -3
    • Change in y: y' - y = 8 - 2 = 6
    • Thus, the translation vector \( \vec{T} \) is (-3, 6).
  3. Apply the translation vector to point B: Now, we apply this translation vector to point B to find point B'.

    • Coordinates of B: (-1, 2)
    • Apply the translation:
      • New x-coordinate: -1 + (-3) = -1 - 3 = -4
      • New y-coordinate: 2 + 6 = 8
    • Therefore, the coordinates of B' are (-4, 8).

So, the coordinates of B' are \(\boxed{(-4, 8)}\).
