    This video goes through all possibilities for two lines running through a plane and what can happen. Terminology is explained for all scenarios. Also, an example problem is worked out and explained.

    There is a glare on the board, making it very difficult to see, and the camera probably needs to zoom in to the board. The sound is quite poor which only adds to the frustration of attempting to follow this lesson.

    I cannot read what is on that black board. I saw another teacher use magnetic numbers. Like the one you put on the fridge. And it was better. And a black marker. Not that!
