A linear equation is a mathematical equation that represents a straight line when graphed on a coordinate plane.
It is characterized by variables raised to the first power and constant coefficients.
The general form of a linear equation in one variable (x) is “ax + b = 0,” where “a” and “b” are constants. In two variables (x and y), a linear equation typically takes the form “ax + by = c,” where “a,” “b,” and “c” are constants.
Linear equations are fundamental in algebra and are used to describe relationships between variables in various real-world situations, such as linear functions and simple linear modeling.
