Target A: Translate Between Multiple Representations of Linear Functions Using Function Notation
Secret Codes in ancient Egypt. The Rosetta Stone, not the language learning software, pictured here has inscriptions of the same text in three different languages: Greek, Egyptian hieroglyphics and Egyptian. These multiple representations allowed language researchers to translate the code of hieroglyphics.

Throughout history cryptography, writing and solving codes, has played an important role in communication and technology. For example, the image to the left is a coding table or cipher that Thomas Jefferson created. Each row of letters is related to a coded letter in the column. This method of coding letters to other letters was used even during World War II. || || New representations of messages can be made using a letter shift coding cipher. Use the app below to encode and decode messages. Begin by encoding **i love math** and decoding **mrsmkqy** media type="custom" key="27802367" Adapted from the GeoGebra work of Bodelot

Decode the quote below **mahlx pah wtkx mh ytbe fblxktuer vtg tvabxox zkxtmer chag y dxggxwr**

Use the coding cipher to encode your own message or quote.
