Linear Equation III

By right-clicking, holding and dragging the line or either of the points A or B, you can:
i) Move the line without rotation
ii) Rotate the line -- the pivot point will be the other point
iii) Slide the point along the line

If you make point A the y-intercept, then rotating the line with point B changes the slope but not the y intercept.

Look for other informative behaviors and activities.
