Without an equality sign the given expression is not an equation
If you mean y = 2x then it is a straight line equation
It is certainly not an equation since there is no equality sign in evidence anywhere. It could be non-linear.
This equation is linear, because neither variable symbol occurs to any power except the first.
With no equality sign the given expression is not an equation
A linear equation has no higher powers than 1. This is linear.

Yes
A nonlinear equation does not produce a straight line and the exponent is to the second power or more. x square plus 3y =5 is an example of a nonlinear equation.
linear system is like a chemistry equation or math equation where on both sides it must balance. Nonlinear is a math equation or physics that does not appear to have a direct answer just like chaos theory. lulu254ever
Hard to tell because of problems with the browser. If the question is about "y = 0" the answer is YES.
Using the line of best fit, yes.
The general equation for a linear approximation is f(x) ≈ f(x0) + f'(x0)(x-x0) where f(x0) is the value of the function at x0 and f'(x0) is the derivative at x0. This describes a tangent line used to approximate the function. In higher order functions, the same concept can be applied. f(x,y) ≈ f(x0,y0) + fx(x0,y0)(x-x0) + fy(x0,y0)(y-y0) where f(x0,y0) is the value of the function at (x0,y0), fx(x0,y0) is the partial derivative with respect to x at (x0,y0), and fy(x0,y0) is the partial derivative with respect to y at (x0,y0). This describes a tangent plane used to approximate a surface.
It is certainly not an equation since there is no equality sign in evidence anywhere. It could be non-linear.
Give us the whole equation, and we can help.
