Unit 3: Linear Models—understanding linearity in real-world contexts.
The emphasis in this unit is on linear models of real-world relations, not on solving linear equations or simplifying linear expressions. Understanding linearity by looking at realistic situations will make manipulating of symbols in future units much more meaningful to you.
