Solving Systems of Equations Graphically

The video tutorial explains how to solve a system of equations by graphing. It covers converting equations to slope-intercept form, graphing each equation, and identifying the intersection point as the solution. The tutorial also demonstrates how to verify the solution by substituting the intersection point back into the original equations.

What is the solution to a system of equations when the lines do not intersect?

• There are infinite solutions.

• There are two solutions.

• There is no solution.

• There is one solution.
