To answer the question, I would need to see the graph of the system of linear equations to determine the best estimate for the solution, which is the point where the lines intersect. However, since the graph is not provided, I can't visually analyze it.
Could you describe the location of the intersection point or give additional details about the lines represented in the graph? Alternatively, if you can provide a brief description of the graph, I might be able to infer the most likely ordered pair.
