A differential equation is given along with the field or problem area in which it arises. Classify it as an ordinary differential equation (ODE) or a partial differential equation (PDE), give the order, and indicate the independent and dependent variables. If the equation is an ordinary differential equation, indicate whether the equation is linear or nonlinear.

The question is incomplete. Here is the complete question.

A differential equation is given along with the field of problem area which it arises. Classify it as an ordinary differential equation (ODE) or a partial different equation (PDE), give the order, and indicate the independent and dependent variables. If the equation is an ordinary differential equation, indicate whether the equation is linear or nonlinear.

(aerodynamics, stress analysis)

Answer and Step-by-step explanation: The differential equation described above is an Ordinary Differential Equation, because it has a definite set of variables: x and y.

It is of Second Order, since the highest derivative is of order 2:

The differential equation is written as derivative of a function y in terms of x, which means: Independent Variable is X and Dependent Variable is Y.

As it is an ODE, the equation is Nonlinear, because y'' or is multiplied by a variable.

the first one, all those points on the line just make a strait line.
