1 answer

To find the new position of point \( A(-6, -6) \) after the specified transformations, we can break it down into two steps: the translation and the reflection.

  1. Translation:

    • Moving 2 units to the right means we add 2 to the x-coordinate.
    • Moving 1 unit up means we add 1 to the y-coordinate.

    Starting with point \( A(-6, -6) \): \[ x' = -6 + 2 = -4 \] \[ y' = -6 + 1 = -5 \] After the translation, point \( A \) moves to \( A'(-4, -5) \).

  2. Reflection over the x-axis:

    • When reflecting a point over the x-axis, the x-coordinate remains the same, while the y-coordinate changes sign.

    Starting with point \( A'(-4, -5) \): \[ x'' = -4 \] \[ y'' = -(-5) = 5 \] After the reflection, point \( A \) moves to \( A''(-4, 5) \).

Thus, after the translation and reflection, the final position of point \( A \) is: \[ \boxed{(-4, 5)} \]
