Question

A linear equation is _______.

• A. an equation with only one term always
• B. an equation with degree 1
• C. an equation with only one variable
• D. an equation with only two terms

Answer 1

The correct option is B an equation with degree 1

If an equation has the degree as one, then that equation is called a linear equation.

For example, 2x + 1 = 7 is a linear equation where the highest exponent of the variable is one.

An equation can have more than two terms and more than one variable.
Eg: $4x+5y+6=0$
