Question

If the figure below were reflected across the waxis, what would be the new coordinates of point A

Answer 1

The coordinates of point A are (-2,3). A reflection across the y-axis is given by:

$(x,y)\rightarrow(-x,y)$

Applying this rule to point A we have:

$(-2,3)\rightarrow(2,3)$

Therefore, the image of point A is (2,3) and the correct option is B.
