Linear Explorer

Change the graph by dragging the red or yellow “ball” to move the end points of the line segment. Linear Explorer immediately displays the equation of the resulting line in slope-intercept format.

Arrow buttons allow fine-tuning the equation one pixel at a time.

Ask yourself “What happens if …?” questions.

• What happens if the line parallel to the x axis? The y axis?

• What does the equation look like when the slope is 1?

• What are the x and y intercepts of a particular line? And so forth …

A BASICS button pops up a quick review of slope-intercept concepts.

A READ button displays full instructions as well some information regarding the development of the Linear Explorer app.
