Algebra 1 Vocabulary

In short: Algebra 1 vocabulary: 49 terms on equations, inequalities, systems, linear and quadratic functions, and polynomials, each defined in plain words with a worked example to clarify any problem statement.
Algebra 1 introduces many words at once, and this algebra 1 vocabulary list keeps them straight: coefficient, like terms, domain, range, slope-intercept form, system of equations, polynomial, factor, vertex. Each entry has a concise definition and a short worked example, so you see the word in action rather than only memorizing it.
Use the page during homework when a problem says “identify the quadratic’s axis of symmetry” and you need a reminder of what that means. Print it before a quiz or final, then cover the answers and test yourself. If you can say the definition and give your own example, you are ready for that word.
49 words on this page, each with a definition, a figure, a solved example and two quick questions.
