Linear Equations: The Five-Step Method That Solves Every “Find x”

Every solve-for-x problem on the Algebra 1 CBE comes down to the same five moves — distribute, combine, isolate, divide, check. Master the order and you'll handle one-step through both-sides equations on autopilot.

Linear Inequalities: Solving, Graphing, and the One Sign-Flip Rule

Inequalities solve like equations — except for one twist. Multiply or divide by a negative and the inequality sign flips. Master that single rule and you'll solve every CBE inequality on autopilot.

Slope & Linear Graphs: Rise Over Run, Three Equation Forms

Slope is rate of change — and rate of change is the entire point of Algebra 1. Master the slope formula, the three line equations (slope-intercept, point-slope, standard), and when to use each.

Systems of Equations: Three Methods, One Intersection Point

A system of equations asks where two lines cross. Three ways to find that point — graphing, substitution, elimination — and how to recognize when there are zero, one, or infinite solutions.

Functions & Notation: f(x), Domain, Range, and the Vertical Line Test

A function is a rule that takes one input and gives one output. Master f(x) notation, domain/range, and the vertical line test — the foundation for every equation and graph in Algebra 1.

Polynomials & Factoring: FOIL, GCF, and the Three Patterns

Multiply binomials with FOIL, then run the process backward to factor. Three patterns cover most CBE factoring questions: GCF, trinomial (x² + bx + c), and difference of squares.
