Students investigate linear functions with positive slopes by trying to guess the slope and intercept from inputs and outputs. Positive Linear Function Machine is one of the Interactivate assessment explorers.
This worksheet is for use with the Function Flyer activity (http://www.shodor.org/interactivate/activities/FunctionFlyer/).
Graphit (Activity)
Create graphs of functions and sets of ordered pairs on the same coordinate plane. This is like a graphing calculator with advanced viewing options.
Vertical Line Test (Activity)
Learn about the vertical line test for functions by trying to connect points in the plane to build a function. When you have connected all of the points, you will be told if your graph is a valid graph of a function. Vertical Line Test is one of the Interactivate assessment explorers.
This worksheet is for use with the Two Variable Function Pump activity (http://www.shodor.org/interactivate/activities/TwoVariableFunction/).

Number Cruncher (Activity)
Similar to the original "Function Machine" but lists input and output in a table and will not let the user attempt to guess the rule without having at least two data points. Number Cruncher is one of the Interactivate assessment explorers.
Linear Functions (Discussion)
Discusses functions of the form y = ___*x + ___.
Teaches distinguishing between possible and impossible graphs of functions as well as causes of graphical impossibility.
