equation mode. A dot will appear on the Eq button at the bottom of the screen.

In equation mode, you use the cursor keys to

move between parameters in the equation and change their values, observing the effect on the graph displayed. Press \or =to decrease or increase the value of the selected parameter. Press >or <to select another parameter. PressQto change the sign of a.

Test mode	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 graph.
	Tap	to see the correct answer and tap		to
	exit Test mode.
