The system of equations plotted on graph 3 has two solutions.
What is a system of equation?
A system of equations is a set or collection of equations that you deal with all together at once. For a system to have a unique solution, the number of equations must equal the number of unknowns.
For the given situation,
Three graphs are shown in the figure.
Here a parabola and a line is plotted on the graph.
The intersection of the parabola and the line indicates the solution of that system of equations.
Graph 1:
In graph 1, the parabola and the line do not intersect at each other. So the equation has no solution.
Graph 2:
In graph 2, the parabola and the line intersect each other at one point. So the equation has one solution.
Graph 3:
In graph 3, the parabola and the line intersect each other at two points. So the equation has two solutions.
Hence we can conclude that the system of equations plotted on graph 3 has two solutions.
