## Solving systems
# Activity Guidelines
##
We know that two lines that are not parallel intersect at exactly one point.
Each student will be given the equation of a line in the plane.
The goal: identify three lines that intersect all at the same point. There are two such triples.
The rules:
- You may not show anyone else your equation.
- You may only communicate with students seated adjacent to you (L and R)
- You and an adjacent neighbor may switch seats at any time.
Protocol:
- Three students must be seated adjacent to win. Tell me when that happens.
- There is a HUGE penalty for guessing. Work with your neighbor to verify solutions. Do not allow yourself to be misidentified as a part of a winning triple.
- After finding a triple, work on supplemental exercises.
- The remaining five students will continue to seek the other triple.
The equations: should we play "Whose line ...?
