Start with a method you can explain. These free guides show what to enter, which result to read, and how to check it. Each includes an original SAT-style practice question with its solution.
How to use Desmos on SAT Math
Learn when to graph, fit a model, or use algebra on SAT Math, with an original worked equation and calculator steps.
Solve SAT systems of equations with Desmos
Graph two equations, read their intersection, and check the coordinates. Compare the same original system with elimination.
When to use regression on SAT Math in Desmos
Fit an original quadratic table in Desmos, evaluate the fitted function, and understand when a fitted model is justified.
Solve SAT quadratic questions with Desmos
Use a parabola's vertex and intercepts to answer SAT-style quadratic questions, with a checked example and algebra comparison.
Have a question to work through?
SolvePlot turns an uploaded or typed question into calculator steps and explanations. You can browse the workspace before signing in.
What should you practise first?
If you are new to Desmos, start with the SAT overview, then learn intersections and quadratic features. Try regression when a question supplies a model with unknown parameters. The interactive Desmos skills lessons provide guided checks and editable calculators after sign-in.
These examples teach the methods; they are original SolvePlot exercises, not official SAT questions. For the test-day calculator, practise in Bluebook and follow College Board’s current calculator policy.
