Solve systems of linear equations exactly and approximately (e.g., with graphs), focusing on pairs of linear equations in two variables. By the end of this playlist, students will be able to understand and solve problems involving linear equations. The playlist is an excellent resource for students to review or study for a test or final.
These videos each cover specific topics and concepts learned in Algebra I classes. Teachers can use these videos to support their lesson plans and engage students. Understand connections between algebraic and graphical representations.įor tutorials and practice questions of all these types, go to Official SAT Practice on Khan Academy at playlist consists of 22 videos all about systems of linear equations. Interpret the variables and constants in expressions for linear functions. Heart of Algebra includes the following types of questions:Ĭreate, solve, or interpret a linear expression or equation in 1 variable.Ĭreate, solve, or interpret linear inequalities in 1 variable.īuild a linear function that models a linear relationship between 2 quantities.Ĭreate, solve, and interpret systems of linear inequalities in 2 variables.Ĭreate, solve, and interpret systems of 2 linear equations in 2 variables.Īlgebraically solve linear equations (or inequalities) in 1 variable.Īlgebraically solve systems of 2 linear equations in 2 variables. These questions ask you to create equations that represent a situation, solve equations and systems of equations, and make connections between different representations of linear relationships. Heart of Algebra focuses on linear equations, systems of linear equations, and functions.
