A linear equation is an equation that describes a straight line on a graph. Explore and learn more about linear equations with concepts, definitions, facts, examples, and solutions.

A linear equation is an equation for a straight line. Let us look more closely at one example: The graph of y = 2x+1 is a straight line. And so:

The phrase "linear equation" takes its origin in this correspondence between lines and equations: a linear equation in two variables is an equation whose solutions form a line. If b ≠ 0, the line is …

A linear equation is an algebraic equation that contains variables that have an exponent that is not higher than one. A linear equation is called linear because when you plot the graph of the …

Jul 23, 2025 · A linear equation is a fundamental concept in algebra that represents a straight line in coordinate geometry. It is a first-order equation, meaning the highest power of the variable is 1.

Nov 7, 2024 · Learn what is a linear equation in algebra with this beginner-friendly guide. Discover the key concepts, examples with graphs and tips.

Aug 21, 2025 · At their core, linear equations represent a straight-line relationship between variables. They are simple yet powerful tools that help us understand patterns, make …

Linear equations are a combination of constants and variables. Linear equation in one variable has the standard form A x + B = 0, where A and B are constants (A≠0), x is the variable. A …

Each term is either a constant, or the product of a constant and a single variable. A linear equation can have one or more dependent variables. For example, the following equation …

We will now equate two algebraic expressions and think about how it might constrain what value the variables can take on. The algebraic manipulation you learn here really is the heart of …
