A linear equation is a fundamental concept in algebra that represents a straight line on a graph. It typically takes the form \( ax + b = 0 \) for a single variable, or \( ax + by + c = 0 \) for two variables, where \( a \), \( b \), and \( c \) are constants, and \( x \) and \( y \) are variables. These equations model proportional relationships and are essential for solving problems in fields like physics, economics, and engineering, as they describe constant rates of change. For example, the equation \( y = 2x + 3 \) shows a line with a slope of 2 and a y-intercept at 3, illustrating how one quantity changes linearly with another.
