Original equation given to graph is:
z = √(x^2 + y^2)

I squared both sides to get:
z^2 = x^2 + y^2

I subtract z^2 from both sides to get all variables on the same side and I get:
x^2 + y^2 - z^2 = 0

Can this be graphed? I'm wanting to answer this question as the graph "DNE" (does not exist). Is that right, or am I totally missing something here?
If I did traces, the equations would all still equal zero ...
So would this 'graph' then just be a point (the origin) instead of DNE?

Thank you for your time and help. :)

I have this weird buzz... almost dizzy but pretty much just a buzz. It started yesterday and it's gotten stronger today. I stopped taking my anti-depressants (woo-hoo!) 5 days ago... could this be why? I can't think of anything else... I haven't been drinking or been on anything else. There has been no other change except for the anti-depressants.

There is a triangle with points A(2,-3), B(6,5), and C (0,5). The triangle is inscribed in a circle. (I don't know if the circle is important because a previous step told me to do that.) The area of the triangle is 21. 1 units^2 through Herons formula. I'll provide the slopes just in case. AB: square root (80) BC: 6 CA: Square root (68). The question is find the coefficients a, b, and c in the equation y=ax^2+bx+c so that the graph of the equation contains points A, B, C. I think that I somehow have to use matrices to solve. If anyone has any idea on how to solve it. Please, don't feel shy to share. I'm desperate.
