How do you know which linear function is the steepest when given the rule? What does a linear function that has negative x values and positive y values look like? How can you describe data that is in graph form? How would you use a function to determine an output? How can you use an equation to make an input/output table? What is the difference between a positive and a negative slope?

What did you learn about functions in the game? What are the different ways a function can be represented? The functions in the game were called "linear functions" - why do you think this is an appropriate name for these functions? How do you know which linear function is the steepest when given a table of values? What rule would you need to apply in order to have an input of 0 and a positive output? How can you tell just by looking at the graph if the line has a positive or negative rate of change?
