Solving Systems of Equations

How can you interpret the number of solutions to a system of equations graphically?

• By looking at the intersection points of the graphs representing the equations.

• By determining the area under the graph.

• By calculating the slope of the lines in the graph.

• By counting the number of lines in the graph.
