• The only graph question with a shaded something that I remember seeing on the SAT was about systems of inequalities. I'm not sure if giving you a graph with a shaded area and asking you to find the area of that is tested or not.
When you graph an inequality, you graph the line and then shade the area, either below or above the line, that corresponds to all the solutions to that inequality. When you graph a system of inequalities, you just graph and shade the area for both lines, and the doubly-shaded area that's overlapping between the two will be the solution to that inequality. A question like this may give you one such graph of a system of inequalities and ask you if a given point is a solution to the system. If the point is within the doubly-shaded part, it is a solution, and if not, it's not.
Is that what you were looking for?
