Answer:

(3,-4)

Explanation:

The rule to follow for reflecting a figure across the y-axis is to take the original coordinate (x, y) and change it to (−x, y)

Answer:

(3,-4)

Explanation:

There is a graphing calculator called desmos that can help you answer questions like this, but, if you don't want to use that, you can just make a graph and imagine the transformation. Remember, when you reflect something over an axis, it is like you are folding the graph along the axis and your new point will be on the other side.
