Question

What is a linear equation in $2$ variables?

• A. An equation containing $2$ variables raised to the power $1$
• B. An equation in which the variables are power $2$
• C. An expression containing $2$ variables
• D. None of the above

Answer 1

Answer: (A)

An equation containing $2$ variables raised to the power $1$

An equation which has two variables and highest power of the variables is $1$ is called a linear equation in 2 variables.

i.e An equation containing 2 variables raised to the power is a linear equation in 2 variables.

Hence, option A is correct.
