linear equation
First-degree algebraic expression
A linear equation is an algebraic equation where each term is either a constant or a variable raised to the first power—no squares, cubes, or higher exponents.
When graphed, it produces a straight line: y = 2x + 3.
Linear equations model proportional relationships and form the foundation for more complex mathematics.
