Answer:
A' = (-1, 6)
B' = (-2, 1).
C' = (-5, 2).
Step-by-step explanation:
Reflection over the y-axis---> (a, b) transforms to (-a, b).
So A (1, 6) ---> A' (-1, 6).
Reflecting across the y axis means to change the sign of the x coordinate:
[tex](x,y)\mapsto (-x,y)[/tex]
For example, point A is (1,6), and it becomes (-1,6).
Do the same with points B and C and you'll have the coordinates of the transformed points.
