Essential Questions
- How can you graph a system of two linear equations on the coordinate plane?
- What does the point where two lines intersect represent when graphing a system of equations?
- How can you tell from the graph if a system of equations has one solution, no solution, or infinitely many solutions?
- In what situations might graphing be a helpful strategy for solving systems of equations?
- How do the characteristics of the lines (parallel, coincident, intersecting) affect the number of solutions to a system?
