Solving Systems of Equations by Graphing

Mrs. Ray introduces solving systems of equations by graphing, focusing on understanding linear equations and their intersection points. Key vocabulary includes consistent, inconsistent, independent, and dependent systems. The video explains different types of solutions, such as one solution, infinitely many solutions, and no solution, and demonstrates how to solve systems by graphing, identifying the point of intersection as the solution.
