Final answer:
The methods to solve a linear system mentioned in class are the graphical method and the algebraic method, involving the use of graphs and algebraic techniques respectively.
Step-by-step explanation:
There are several methods used to solve a linear system. The methods used in class sessions to solve such a system are the graphical method and the algebraic method.
The graphical method involves plotting the equations on a graph and finding the point where they intersect, which would be the solution of the system.
The algebraic method includes techniques like substitution, elimination, and using matrices to find the solution. In both methods, we create and solve equations that represent relationships, identify knowns and unknowns, and manipulate the equations to solve for the unknowns.
