The video tutorial explores how to determine the number of solutions in a system of linear equations using both graphical and algebraic methods. It covers scenarios with no solutions (parallel lines), infinite solutions (identical lines), and one solution (unique intersection). The tutorial provides step-by-step algebraic solutions and explains the graphical interpretation of each case.

What are the possible outcomes when solving a system of linear equations graphically?

• Only no solutions

• Only infinitely many solutions

• Only one solution

• No solutions, one solution, or infinitely many solutions
