Graph the image of the polygon after a reflection in the line y = t.

Answer:
see the attached
Step-by-step explanation:
Reflection over a line moves each point so that the segment between it and its image has the reflection line as its perpendicular bisector.
The line of reflection y=x has the effect of swapping the x- and y-coordinates:
(x, y) ⇒ (y, x) . . . . . reflection in y=x
For example, point C(2, 3) moves to point C'(3, 2).
The attachment shows the reflected figure.
