It is an equation. It could be an algebraic equation, or a trigonometric equation, a differential equation or whatever, but it is still an equation.
No. In the variable x, alone, it is linear. In the variable y, alone, it is linear. But taken together, in x and y, you have a term which contains xy - that is, a term in which the powers of the unknowns add to 2. So the equation is not linear.
The quadratic formula cannot be used to solve an equation if the coefficient of the equation's x2-term is 0.
an equation that shows how to calculate the value of the next term in a sequence from the value of the current term
No, it's a cubic equation. A quadratic equation contains, as its term raised to the highest power, a square. Example: x2. A cubic equation contains, as its term raised to the highest power, a cube. Example: x3. A quartic equation contains, as its term raised to the highest power, a term raised to the fourth power. Example: x4. Quintic, x5. And so, on.

An equation of the second degree, meaning it contains at least one term that is squared.
In a mathematical equation, the constant is defined as a term in the equation that only includes a real number. Since a negative number is a real number, then yes, a negative number can be considered a constant. For example, in the equation 6x -2... -2 would be the constant because it is a term that contains only the real number (-2).
An algebraic equation.
