A 線形方程式 is a mathematical equation that represents a straight line when graphed on a coordinate plane. It is typically expressed in the form y = mx + b, where y is the dependent variable, x is the independent variable, m is the slope of the line, and b is the y-intercept. The slope indicates the steepness of the line, while the y-intercept represents the point where the line crosses the y-axis.
Linear equations can involve one or more variables. For example, a simple linear equation in one variable can be represented as ax + b = 0, where a and b are constants and x is the variable. In the context of two variables, a linear equation describes a relationship between those variables, showing how a change in one affects the other.
