Some practice solving systems graphically ![]() (+) Find the inverse of a matrix if it exists and use it to solve systems of linear equations (using technology for matrices of dimension 3 × 3 or greater). (+) Represent a system of linear equations as a single matrix equation in a vector variable. For example, find the points of intersection between the line y = -3x and the circle x2 + y2 = 3. Solve a simple system consisting of a linear equation and a quadratic equation in two variables algebraically and graphically. 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. This playlist consists of 22 videos all about systems of linear equations.
