Estimating Solutions of Systems of Equations by Graphing

This video tutorial teaches how to estimate the solution of a system of equations by graphing. It reviews graphing lines using intercepts and explains how to find intercepts by substituting zero for variables. The tutorial covers the concept of systems of equations, their solutions, and how the intersection of lines represents these solutions. It also addresses common misunderstandings, such as the belief that all systems have solutions, and explains scenarios with no solutions or infinitely many solutions. The video emphasizes estimating solutions graphically, especially when solutions are not integers, and highlights the importance of checking algebraic solutions with graphs.
