Algebra 1 help
Free Algebra 1 help with equations, functions, slope, systems, exponents, and quadratics. Find step-by-step examples and practice for each topic.
Where to start
Start with simplifying expressions and solving equations if you need a foundation. For graphing, review coordinates and functions before slope and linear equations. Factoring and exponent rules prepare you for quadratics later in the course.
After solving an equation, substitute the answer into the original equation. After graphing a line, check a second point. These quick checks help you tell an arithmetic slip from a step you need to review.
