Step 2

A linear equation is an equation of a straight line, which means that the degree of a linear equation must be

$0$ or

$1$ for each of its variables. In this case, the degree of variable

$y$ is

$1$ , the degrees of the variables in the equation violate the linear equation definition, which means that the equation is not a linear equation.
