**TEKS**- A.2(I) – write systems of two linear equations given a table of values, a graph, and a verbal description
- A.3(F) – graph systems of two linear equations in two variables on the coordinate plane and determine the solutions if they exist
- A.3(G) – estimate graphically the solutions to systems of two linear equations with two variables in real-world problems
- A.5(C) – solve systems of two linear equations with two variables for mathematical and real-world problems
