Remember:
- Standards A-REI.C.5, A-REI.C.6, A-REI.D.11 and A-CED.A.3: solve systems by graphing, substitution and elimination, and model real situations.
- Two lines meet once, never, or everywhere: one solution, no solution, or infinitely many.
- Substitution works best when a variable is already isolated; elimination works best when coefficients match or are opposites.
- Adding equations is valid because equal quantities added to equal quantities stay equal.
- The x-coordinates where two graphs meet solve \(f(x)=g(x)\) for lines, parabolas and exponentials alike.
