Digital SAT Math: The Circle "Desmos Trap" (Tangents & Translations)

Are you falling for the College Board's Desmos Trap? In this video, we tackle two of the hardest Circle Equation problems on the Digital SAT: finding a point on a tangent line, and translating a circle across the xy-plane.

While Desmos is a great tool, trying to solve these specific problems visually will drain your clock. I will show you exactly why the calculator method is a trap here, and teach you the 10-second algebraic shortcuts to find the slope of the tangent and translate the equation instantly.
