$\textbf{Explanation:}$

A linear regression equation simply sums the terms. While the model must be linear in the parameters, you can raise an independent variable by an exponent to fit a curve. For instance, you can include a squared or cubed term. Nonlinear regression models are anything that doesn't follow this one form.
