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

Key Concepts

System of Equations

A system of equations involves finding values for the variables that satisfy all given equations simultaneously. In algebra, this concept is used to determine where functions intersect or overlap, which provides a common solution for each equation in the system.

Graphical Solution Method

The graphical method for solving systems involves plotting each equation on a coordinate plane and identifying the intersection points of the graphs. These intersections represent the solution set of the system, as they are the points where the equations produce the same output values for the variables.

Conic Sections

Conic sections are curves formed by the intersection of a plane with a double-napped cone. Recognizing the standard form of a conic, such as an ellipse, allows one to graph the curve by determining its central features like axes, vertices, and intercepts, which is crucial when solving systems that include non-linear equations.

Linear Equations

Linear equations represent straight lines and are characterized by a constant rate of change, or slope, and an intercept. Graphing a linear equation helps in understanding its geometric representation and facilitates finding intersection points with other types of curves.

Solution Verification

Verification involves substituting the obtained solutions back into the original equations to ensure they satisfy every equation. This step confirms the accuracy of the graphically determined intersection points, eliminating any potential errors in the solution process.
