The question is missing the figure. So, I have attached the figure below.
Answer:
Explanation:
Line of reflection is nothing but the axis of symmetry for the original shape and its reflected shape.
Here the original shape is a polygon ABCDE. The reflected shape is A'B'C'D'E'.
From the figure, the point D and D' overlap each other. Each point of the original shape is the same distance as that of the reflected point from the y-axis.
Therefore, the axis of symmetry is the vertical y-axis. Hence, this is also the line of reflection of the polygon ABCDE.
The equation of y-axis is given as:
Therefore, the equation for the line of reflection is
