A **Graphing vs. Substitution worksheet** typically involves solving a system of linear equations using two different methods: graphing and substitution. In the **graphing method**, students plot both equations on a coordinate plane and identify the point where the two lines intersect, which represents the solution. In the **substitution method**, one equation is solved for one variable, and that expression is substituted into the other equation to find the values of both variables. The answer key provides the solutions to the system using both techniques, showing step-by-step procedures, including graphing points, solving for variables, and verifying the solution for consistency. It may also include specific numerical solutions, such as the coordinates of the intersection or the values of the variables that satisfy both equations.
