Question

the point b is a reflection of point a across which axis? choose 1 answer:

Explanation:

Step1: Observe point coordinates

Point A has a negative y - value and point B has a positive y - value with similar x - values.

Step2: Recall reflection rules

Reflection across the x - axis changes the sign of the y - coordinate. Reflection across the y - axis changes the sign of the x - coordinate. Since only the y - coordinate's sign changes from A to B, it is a reflection across the x - axis.

Answer:

The x - axis
