key term - Solution Region

Definition

The solution region, in the context of systems of nonlinear equations and inequalities with two variables, refers to the set of all points (x, y) that satisfy the given system of equations and/or inequalities. It represents the area or region in the coordinate plane where the solutions to the system can be found.
