The first graph represents a system of equations with aunique solution.
The second graph represents a system of equations with no solutions.
The third graph represents a system of equations with infinitely many solutions.
The fourth graph represents a system of equations with a unique solution.
The first graph shows a system of equations that has a unique solution because the two linear graphs have a single point of intersection.
The second graph shows a system of equations with no solutions. This is because the two graphs are parallel to each other, and have no point of intersection.
The third graph has two linear equations that coincide at every point. This makes this system to have an infinite number of solutions.
The fourth graph shows two linear functions having a single point of intersection. This particular system of equations has a unique solution.
