Question

1. determine the correct answer. determine the coordinates for a after a reflection over the x-axis.

Explanation:

Step1: Find original coordinates of A

Assume grid units: A is (-2, 1) (2 left, 1 up from origin).

Step2: Apply reflection over x-axis rule

Rule: (x, y) → (x, -y). So (-2, 1) → (-2, -1).

Answer:

(-2, -1)
