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.
When a system of linear equations in standard form (\( Ax + By = C \)) has infinitely many solutions, it means the two equations describe the exact same line. Therefore, their \( x \)-coefficients, \( y \)-coefficients, and constants must a...
