x = ±2
It is the Cartesian equation of an ellipse.

no
The 'x' and 'y' intercepts of that equation are both at the origin.
Because when your solving a quadratic equation your looking for x-intercepts which is where why equals 0 and x equals what ever the answer is.
If a = b then it is a circle; otherwise it is an ellipse.
No, It's a a quadratic equation because you have X squared.
It is a quadratic equation in X.
no, because xx=x squared, and x squared is not linear
If the equation is 7x - 3y = 21 then (3, 0) and (0, -7).
This is not possible, since the point (4,6) lies inside the circle : X2 + Y2 = 16 Tangents to a circle or ellipse never pass through the circle
Yes it is. The thing that makes it a quadratic equation is that "x squared" in there.
