find the solution set for each system by
graphing both of the system's equations in the same rectangular coordinate system and finding points of intersection. Check all solutions in both equations.
$\left\{\begin{array}{l}x=(y-2)^{2}-4 \\ y=-\frac{1}{2} x\end{array}\right.$

Key Concepts

Solution Verification

Solution verification involves substituting the obtained results back into the original equations to ensure they satisfy all the conditions of the system. This step is critical to confirm the accuracy and validity of the solutions obtained from either the graphing method or algebraic techniques.

Intersection Points

Intersection points of graphs are the coordinates where two or more functions meet, meaning they satisfy all equations in the system simultaneously. Identifying these points both graphically and algebraically is a key strategy in solving systems of equations.

Linear Function

A linear function represents a straight line on the coordinate plane, characterized by its slope and y-intercept. The simplicity of a straight line makes it easier to identify intersections with more complex curves, such as parabolas, as the line’s behavior directly influences where and how it crosses other graphs.

System of Equations

A system of equations consists of multiple equations with common variables. The goal is to find one or more solutions that simultaneously satisfy all equations in the system. This concept is essential in algebra and calculus, as it models situations where multiple conditions or constraints occur at the same time.

Graphing Equations

Graphing equations involves plotting them on a coordinate plane to visually assess the behavior and relationship between functions. This technique is particularly useful for understanding how functions interact, such as determining points of intersection that represent solutions to a system.

Quadratic Function (Parabola)

A quadratic function, when expressed in a form that relates one variable as a function of a quadratic expression in another, generates a parabolic graph. Understanding the shape, orientation, and vertex of a parabola helps in predicting where it might intersect with other functions, like a linear equation.
