Linear Inequality Game
Inspired by Dan Meyer's post:

In this game you're trying to guess a linear inequality by guessing points.
When you find a true point, you can guess the inequality.
The applet always picks a line through two visible points with integer coordinates. So it is very helpful to be able to find an equation of a line through two points. Most of my guesses look like y <= (slope)(x- xcoordinate) + ycoordinate.
