[Foundation and Higher] Find approximate solutions to simultaneous equations using a graph.

[Foundation and Higher] Find approximate solutions to simultaneous equations using a graph. is assessed within Solving equations and inequalities. Graphical simultaneous equations are solved at the intersection of two graphs, where both equations are true at the same point. A complete answer identifies the two graphs, locates their crossing, and gives the coordinate pair rather than only one value. This differs from single-equation graphical solving because the answer is the shared point for two relationships, not just a root or intercept. For exam answers, show the chosen representation, calculation step or graph reading before giving the final value.
