## Unit 2 - Linear Systems

**By the end of this unit, students will be able to s**olve a system of linear equations using a variety of strategies, solve problems that are modelled by linear equations or systems of linear equations, and describe the relationship between the number of solutions to a system of linear equations and the coefficients of the equations.
