Systems of Equations Unit
UNIT OBJECTIVES: From New Illinois Mathematics Standards 8.EE.8a, 8.EE.8b, 8.EE.8c
Analyze and solve pairs of simultaneous linear equations:
- Understand that solutions to a system of two linear equations in two variables correspond to points of intersection of their graphs because points of intersection satisfy both equations simultaneously.
- Solve systems of two linear equations in two variables algebraically, and estimate solutions by graphing the equations.
- Solve real-world mathematical problems leading to two linear equations in two variables.
