Solving Systems of Equations Graphically

The video tutorial explains how to solve systems of equations by graphing. It introduces the concept of systems of equations and solutions, demonstrates how to verify solutions, and provides an overview of the graphing method. The tutorial includes examples of graphing systems to find solutions, highlighting different outcomes such as one solution, no solution, and infinite solutions. The video also briefly mentions other methods like substitution and elimination for future learning.

What is a system of equations?

• A single equation with multiple variables.

• A set of equations that cannot be solved.

• A single equation with one variable.

• A set of equations with the same variables.

What does it mean for an ordered pair to be a solution to a system of equations?

• It makes both equations true.

• It makes both equations false.

• It makes neither equation true.

• It makes only one of the equations true.

What is the first step in solving a system of equations by graphing?
