In this unit, students will model a situation with a linear system and use the equations to solve a related problem. They will graph a linear system with and without the use of technology. Students will discover that the point of intersection of the graph is the solution of the linear system. They will verify the solution by checking that the coordinates satisfy both equations in the linear system. Students will also investigate both the algebraic strategies of substitution and elimination when solving linear systems. When the different methods in solving a system of equations has been introduced, students will be able to identify the most efficient method appropriate for the system of equations being solved. Students will explore linear systems with no solutions, one solution and an infinite number of solutiions. They can use graphing or examine the slope-interecept form of the linear equation to determine the number of solutions for a linear system.
