Identify and draw the following graph:
2x^2 + y^2 - 4x + 4y + 6 = 0

Completed the square, and I got:
2(x+1)^2 + (y+2)^2 = 0

I realized that the number in front of the bracket won't go away, so I divided everything by 2.
(x+1)^2 + (y + 2)^2/2 = 0

So it is an ellipse, but not with a radius of 1. So I searched this case up and found that is a "degenerate ellipse", but couldn't find any good procedure for drawing this.

How would you go about with drawing this?
