The solution graph is the entire set of “ordered pairs” that satisfy the equation. One example is (0, -1).
Explanation:
Pick any point on the equation curve and use the graph coordinates to identify any ordered pair. You can also do that non-graphically by simply solving the equation for any (x,y) pair. For example, if x is 0, y is -1. The ordered-pair solution is (0,-1). Similarly, for x=1 we derive (1,-(1/3)).
That is actually how the curve is constructed from the values, but if you have a given graph with sufficient resolution in the area of interest, you can obtain ordered-pair solutions directly from the graph.
