What is the Highest Degree of Linear Equation?

The highest degree of a linear equation is 1. In mathematics, a linear equation is an equation in which the highest power of the variable (usually represented as "x") is 1. Linear equations can be written in the form of:

ax + b = 0

Where "a" and "b" are constants, and "x" is the variable. The exponent on "x" is 1, making it a first-degree equation. Linear equations represent straight lines when graphed on a coordinate plane, and they have a constant rate of change. Any equation with a higher degree for the variable (e.g., x^2, x^3, etc.) is considered a non-linear equation.
