Overview

Linear equations in two variables extend our understanding from single-variable equations to equations involving two unknowns. Unlike linear equations in one variable that have a unique solution, linear equations in two variables have infinitely many solutions that form a straight line when graphed.

Key Concepts

A linear equation in two variables

A linear equation in two variables is an equation that can be written in the form ax + by + c = 0, where a, b, and c are real numbers, and a and b are

A solution is an ordered pair

A solution is an ordered pair (x, y) of real numbers that satisfies the equation when substituted. Unlike one-variable equations, linear equations in

The graph of a linear equation

The graph of a linear equation in two variables is always a straight line. Every point on the line represents a solution to the equation, and every so

Equations of the form x =

Equations of the form x = k represent vertical lines parallel to the y-axis at distance |k| from it. Equations of the form y = k represent horizontal
