Answer:
See below & see pic.
Step-by-step explanation:
To find where a point goes, start with the original point and see how many units it takes to get to the line of reflection in a path perpendicular to that line.
For example, H is 3 units from the line, so go 3 units past the line to find H'.
Do the same for the other points.
You get E'F'G'H' as shown in the figure below.
