i just took the June sat and for one of the questions, i typed in the exact equation “sqrt((x-2)^2+(y-8)^2)=4” and desmos gave me the red squiggly to the left of the equation indicating that it graphed it but on the right side of the screen, no circle came up? did anyone experience something similar or am i misremembering?
