A system of equations represents geometric intersections. Consider substitution, elimination, or setting both expressions equal.
Desmos Tactical Shortcut: Plot the left-hand side and right-hand side as separate equations (e.g. \( y_1 = f(x) \) and \( y_2 = g(x) \)). Click the intersection points directly to read exact coordinates.
The SAT loves testing systems, and a great strategy here is either substitution or elimination. Let's use substitution because the second equation can be easily rearranged to solve for \( y \). Step 1: Isolate \( y \) in the second equation...
