Parallel Lines in the Coordinate Plane: Quick Exploration
- GeoGebra Team
In the applet below,
Once done, please answer the questions that appear below the applet.
|1.||||Use the line tool to construct a line.|
|2.||||Use the parallel line tool to construct a line that is parallel to the line you constructed in (1).|
|3.||||Use the slope tool to measures and display the slopes of both lines.|
|4.||||Select the move tool. Move any one (or more) of these points around.|
From what you've observed, what can we conclude about any two (non-vertical) lines drawn in the coordinate plane?
If a line has a slope of zero, then it
