## What are Linear Equations?

The Equation in which the highest power of the variable is always 1 is known as a linear equation. It is known as a first-degree equation. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, and A, B and C are constants. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, and A and B are constants.
