The answer depends on how you treat $x$ $x$ and $y$ $y$ .

If they are both unknowns, then it is not a linear equation, because one of the unknowns ( $y$ $y$ ) is raised to a power other than 1.
But on the other hand, if you treat $y$ $y$ as a constant (like $e$ $e$ or $π$ $pi$ ) then the only variable ( $x$ $x$ ) is raised to the power 1, and the equation becomes linear.
