This video reviews the graphing method of solving systems of equations.

How many equations are typically involved in a system of equations when using the graphical method?

• 1

• 4

• 3

• 2

Explain how to graphically solve a system of equations with two variables.

• Solve each equation separately and compare the results

• Use a calculator to find the solution

• Guess the solution and plot it on the graph

• Plot both equations on a graph, find the point of intersection, and that point represents the solution.

What does the point of intersection represent in the graphical method of solving systems of equations?

• The point of intersection represents the solution to the system of equations.

• The point of intersection represents the product of the equations

• The point of intersection represents the sum of the equations

• The point of intersection represents the average of the equations
