Overview

A pair of linear equations in two variables is a basic tool for solving situations with two unknown quantities. A linear equation in two variables has the form ax + by + c = 0, where a² + b² ≠ 0. The graph of such an equation is a straight line. When two such equations are considered together, the g

Key Concepts

A linear equation in two variables

A linear equation in two variables has the form ax + by + c = 0, where a² + b² ≠ 0. It represents a straight line on a graph.

Two linear equations in the same

Two linear equations in the same two variables form a pair of linear equations. A pair can be written as a1x + b1y + c1 = 0 and a2x + b2y + c2 = 0, wi

A pair of values of x

A pair of values of x and y that satisfies both equations together is called a solution of the pair.

One equation with two unknowns has

One equation with two unknowns has many solutions. Two independent equations are needed to get a unique solution.

The graph of each linear equation

The graph of each linear equation is a straight line. The point where the two lines meet gives the solution, if they intersect. If the lines are paral
