4. Equation of a Line Game - This is a mathematical activity designed to help students practice finding the equation of a line in slope-intercept form. Press the "go" button to start the game. A green line will appear; select the button with the equation that describes the green line before the time runs out. Selecting the correct button will give you a new line, but less thinking time.
