Answer:

The answer depends on where the point is.

Explanation:

You didn't put enough info to answer it properly. However, because I care, I'll do it backwards.

The first answer is right if point A is at (-3,-1)

The second is right if point A is at (-1,-3)

The third, if point A is at (1,3)

The Fourth, if point A is at (3,-1)

When you reflect across an axis, you use the rules of reflection.

Reflection across the x-axis: (x,-y)

Reflection across the y-axis (-x,y)
