Tap to enter test mode. In Test mode you test your skill at matching an equation to the graph
shown. Test mode is like equation mode in that you use the cursor keys to select and change the value of each
parameter in the equation. The goal is to try to match the graph that is shown.
The app displays the graph of a randomly chosen linear function of the form dictated by your choice of level.
(Tap or to change the level.) Now press the cursor keys to select a parameter and set its
value. When you are ready, tap to see if you have correctly matched your equation to the given
