Thanks. You got right to the point, it instantly clicked for me — after watching this

Nice presentation. I was just looking at x²+y²=9 and found your video. So the graph of this one will have a radius of ol Pythagoras.

as in this you had made a circle on the graph ....
so any picture like rectangles, square, etc what this are realible for make on it

Your monotone voice matches my voice and the voice in my head so I understand it extremely clearly

How can you tell it wouldn't be a rhombus because the points on a rhombus would be similar if you connected the lines differently.

how do you know that the centre will be (0, 0) from just the radius
