Answer:
The line of reflection for this image is the y-axis
Explanation:
we know that
The rule of a reflection of a point across the y-axis is equal to
(x,y) -----> (-x,y)
In this problem we have
the coordinates (4,2),(5,3) and (6,2)
Applying reflection across the y-axis
(4,2) -----> (-4,2)
(5,3) ----> (-5,3)
(6,2) ----> (-6,2)
therefore
The line of reflection for this image is the y-axis
