Goals of the Unit

1. recognize linear and nonlinear patterns from verbal descriptions, tables, and graphs and describe those patterns using words and equations
2. write equations to express linear patterns appearing in tables, graphs, and verbal contexts
3. write a linear equation when given specific information, such as two points or a point and the slope
4. approximate linear data patterns with graph and equation models
5. solve linear equations
6. develop an informal understanding of inequalities
7. write equations describing inverse variation
8. use linear and inverse variation equations to solve problems and to make predictions and decisions
