Question

What is a linear equation is one variable?

• A. An equation containing one variable raised to the power $1$
• B. An equation in which all variables are of power $1$
• C. An expression containing one variable
• D. None of these

Answer 1

The correct option is A An equation containing one variable raised to the power $1$

A linear equation with one variable consists of numbers or constants and multiplies of a variable. The standard form of such an equation is $ax+b=0$, where $a$ and $b$ are constants and $x$ is the variable.

Hence, a linear equation in one variable is an equation containing one variable raised to the power $1$.
