What is the formula for the line of reflection? Remember that you may need to zoom in or out depending on your device. See if you can remember how to find this line from memory. Use whichever tools you need from the tool palette above.
You should have found the line [math]y=3x+3[/math]. If not, go read the instructions before question 3 one more time.[br][br]This line is always perpendicular to the segments connecting the preimage to the image. Since it goes through the mid point, it cuts the segment in half and is a [b]bisector [/b]("bi" means two, and "sector"means cut or pieces). Thus, the line of reflection in always a [b]perpendicular bisector [/b]to the segments connecting the preimage to the image. Cool, huh?
