SDCInfinity

Answer:

E) (-4, -2)

Step-by-step explanation:

Rule for reflecting across the x-axis: (x, y) ⇒ (x, -y)

Therefore, B(-4, 2) ⇒ B'(-4, -2).

Answer:

E) (-4,-2)

Explanation:

When a point is refelected across the x-axis, the x-coordinate remains the same but the y-coordinate changes depending on the quadrant.
