Desmos Basics for the Digital SAT

Why the SAT Emphasizes Desmos Basics for the Digital SAT

Desmos is built into the Digital SAT, which means you always have a graphing calculator at your fingertips. The challenge is not learning every feature, it is knowing the small set of actions that save the most time.

This lesson focuses on those core moves, entering equations, using a table, and reading intersections. Once you can do these smoothly, Desmos becomes a strategic advantage rather than a distraction.

A Simple Definition Unlocks Desmos Basics for the Digital SAT

Desmos reads each line as its own expression. If you enter $y = 2x + 3$, you get a graph. If you enter a calculation like $2(5) + 3$, you get a number. That flexibility is what makes Desmos so powerful on test day.

Tables are another fast tool. If you define $f(x)$, you can create a table of values with a click and read outputs immediately. This is often faster than doing repeated arithmetic by hand.

Work Through Desmos Basics for the Digital SAT Step by Step

Even with Desmos, keep the algebra in mind so you can sanity check the graph or intersection.

Use Desmos to Check Desmos Basics for the Digital SAT

Graph both sides of an equation, then read the $x$ value of the intersection. This is a fast method for many SAT questions.

Desmos is faster when the arithmetic is messy. Algebra is faster when the numbers are clean.

Expert move: Graph the left and right sides directly (no need to isolate $y$), then click the intersection(s) and read the $x$-value(s). Convert decimals to fractions when the choices are exact and keep only context-valid solutions.

Don't overuse Desmos: If the algebra is one or two steps, solve by hand and use Desmos only to verify; it is best for messy coefficients or checking setup.

• Desmos features used: graphing, intersections, tables.
• Common mistake: reading the $y$ value instead of the $x$ value.
