-3
When there are two negative be added your answer will always be negative. In this case add the ones(2) and then add the 1/2s(1) and then add the two. For this you’ll get 3 but just add the negative sign.

Answer:

It is a reflection  across the y axis

The reflection of point (x, y) across the y-axis is (-x, y).
