Answer:

y.

Step-by-step explanation:

When you reflect a point across the x-axis the sign of the y value changes. In the case of reflection across the y-axis the sign of the x value changes. So, for the point A(-2,-3.4) after the reflection the point B(2,-3.4) has the x value with different sign, so is a reflection over the y-axis.
