### Geek of the Week: Christian

This smug young man holding the cup of coffee is our new geek of the week. Everybody wants to use shortcuts in math. The dilemma for math teachers is often short cuts are used improperly resulting in tons of errors. Christian had one such short cut picked out for finding the y-intercept of any line from the slope and a point on the line. I assured him the technique was sound, but warned him that he was likely to screw up if the numbers given weren't nice. He didn't look worried at all, which piqued me, so I threw up a difficult example on the board and bet him a cup of coffee he couldn't find the y-intercept. Of course, he did. This is a picture of him enjoying my humiliation. By the way, if any of you want to congratulate him on his geek eminence, he takes hazelnut, cream, and sugar.
