General Information:[br]Changing the sliders will change the x-coordinate or the y-coordinate (by integers). The coordinates of point A will change accordingly.[br]Dragging the point A will change the coordinates (by tenths).[br]The equation for the horizontal line is in red. The equation for the vertical line is in blue.

To do:[br]1. Use the slider to change the x value. Describe what happens to the red and blue lines.[br]2. Use the slider to change the y value. Describe what happens to the red and blue lines.[br]3. Does the equation x=3 represent a vertical or horizontal line?[br]4. Does the equation y=3 represent a vertical or horizontal line?[br]5. What is the equation of the vertical line through the point (3,5)?[br]6. What is the equation of the horizontal line through the point (3,5)?[br]7. What is the equation of the x-axis?[br]8. What is the equation of the y-axis?
