A. You can't grab the end of a ray to change the slope. Only segments (with an end visible) can be moved in this way. To modify the slope of a ray, you must use the symbolic expression of the ray.
A. Because the two occupy the exact same coordinates, only one can be seen at a time. Click once in the yellow function area and the yellow representation will come "forward" and be visible while the orange is hidden.
A. To convert the infinite end of a ray to a finite value, you must delete the ray and replace it with a line segment of finite domain. Click the ray to select it, then click the Delete button, then click the Segment Creator.

A. Yes. Simply click once on any symbolic representation to bring up the Edit Segment dialog box. Above the symbols you will see two tabs: Slope-Intercept and Point-Slope. Click the Point-Slope tab to use that form; click the Slope-Intercept tab to go back. The numbers will stay the same, allowing you to compare the forms or make changes in either one.
A. Suggestions are always welcome! The best way to introduce your idea is in one of your discussion groups. Your facilitator will note your suggestion for possible inclusion in future versions.
