Question

What would be the transformation of point A when reflected across y-axis?(0, 2)(2, 1)( - 1, 2)(1, - 2)

Answer 1

Given graph has a figure and on that figure there's a point A with co-ordinate (1,2).

Refelection across y-axis :

The rule for reflection over the y-axis is

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

So, according to given graph point A (1,2) has reflection across y axis is (-1,2).

Hence, the required answer is (-1,2).
