Linear Equations in Maths

A linear equation is one in which the highest power of a variable (like x, y, etc.) is 1. For example, x + 10, y + 1, etc.

• It is also known as a one-degree equation.
• The graph of a linear equation is a straight line.
• No variable in the linear equation has an exponent greater than 1.
