Practice

Linear equations

Isolate the variable. Desmos: graph both sides.

Linear models

Translate English to y = mx + b, then evaluate or solve.

Systems of equations

Intersection = solution. One / none / infinitely many.

Inequalities

Shade the region. Test a point. Extrema live on the border.

Functions

f(a) means plug in a. Read graphs at intercepts and vertices.

Quadratics

Roots, vertex, intercepts. Vertex x = −b/2a.

Exponentials

Multiply by the same factor each step. Growth vs decay.

Equivalent expressions

Same graph = same expression. Expand, factor, or regress.

In terms of

Pick a number for the extra letter, then match the choice.

Ratios & percents

Percent of vs percent less than. Part/whole = percent/100.

Data & statistics

mean() and median() in Desmos. Missing value: set the mean.

Scatterplots & lines

Two points → table → linear regression. Slope is the rate.

Geometry

Triangle sum 180°. Similar figures share ratios.

Trigonometry

SOH-CAH-TOA. Switch Desmos to degrees.

Circles

(x − h)² + (y − k)² = r². Graph it and click the endpoints.

Desmos regression

Table + ~ finds coefficients in seconds.

Central ideas

The choice that covers the whole passage without extras.

Details & evidence

The line has to actually say it. Extreme words are traps.

Inferences

Must be true from the text — not a world-knowledge leap.

Words in context

Plug the choice into the sentence. Dictionary #1 often fails.

Structure & purpose

Why is this sentence here? Setup, contrast, example, turn.

Transitions

Read both sides. Contrast, cause, add, or example?

Rhetorical synthesis

Do only what the student wants. Extra facts are wrong.

Boundaries

Two complete sentences need a period, semicolon, or FANBOYS.

Form & structure

Match number, tense, and parallel shape.
