Standard(s): - A.REI.C.6: Solve systems of linear equations exactly and approximately (e.g., with graph), focusing on pairs of linear equations in two variables.
- A.REI.D.11:Explain why the x-coordinates of the points where the graph of the equations y = f(x) and y = g(x) intersect are the solutions of the equation f(x) = g(x); find the solutions approximately, e.g., using technology to graph the functions, make tables of values, or find successive approximations. Include cases where f(x) and/or g(x) are linear, polynomial, rational, absolute value, exponential, and logarithmic functions.*
