Definition

Equations in two variables involve two variables and describe a relationship between them.

Description

Equations in two variables are essential in algebra and coordinate geometry. They typically take the form of 

ax + by = c

and represent lines in a coordinate plane. For example, the equation 

2x + 3y = 6

can be graphed as a line.

These equations are used in real-world applications such as economics, physics, and engineering to model relationships between two quantities. Understanding equations in two variables helps students analyze and interpret data, and solve systems of equations.
