Unit 7 - Systems

Unit Concepts:

• Given a problem in context, write an appropriate system of linear equations or inequalities.
• Solve systems of equations graphically and algebraically, using technology as appropriate.
• Graph the solution set of a system of linear inequalities in two variables.
• Interpret solutions in problem contexts.

Word Wall Defined:

Coefficients: a numerical factor in a term of an algebraic expression.

 

Intersecting Lines: lines that have one point in common or all points in common.

 

Linear Combination Method: a technique for solving a system of equations that involves combining two equations in order to eliminate one of the variables and solving for the remaining variable. Adding, subtracting, or multiplying a system of equations to help solve the system.

 

Substitution Method: a technique for solving a system of equations that involves replacing one variable with an equivalent expression and solving for the remaining variable.

 

System of Linear Equations: two or more equations that together define a relationship between variables usually in a problem situation. A system of equations can have no solution, one solution, or many solutions.

 

System of Inequalities: two or more inequalities that together define a relationship between variables usually in a problem situation. A system of inequalities can have no solution or multiple solutions
