System of Linear Equations

A system of linear equations consists of two or more equations in which each equation is linear, meaning that each variable appears only to the first power and the graphs of these equations are straight lines. This concept is essential as it forms the foundation for understanding how the equations interact, such as determining where their solutions lie in relation to each other.

Graphical Method

The graphical method involves plotting each equation on a coordinate system and identifying the point(s) at which the graphs intersect. This approach provides a visual representation of the solution to the system, illustrating how the equations relate to each other and where they come together, which is particularly useful for understanding the behavior of linear systems.

Unique Solution

A unique solution refers to the single set of values for the variables that satisfies all equations in the system simultaneously. In the context of graphing, this unique solution is represented by the single point where the lines intersect, indicating that the system is consistent and independent, as opposed to having no solution or infinitely many solutions.
