The video tutorial introduces systems of equations, explaining how they consist of two or more equations. It demonstrates graphing linear equations to find intersection points, which represent solutions. Examples include graphing equations like y = 1/3x + 2 and y = -1x + 6, and finding their intersection. Special cases such as parallel lines with no solutions and identical lines with infinite solutions are also discussed.

What is a system of equations?

• An equation with no variables

• Two or more equations considered together

• A graph with no lines

• A single equation with multiple variables
