WebJan 11, 2024 · Standard equation of a circle. The standard, or general, form requires a bit more work than the center-radius form to derive and graph. The standard form equation looks like this: {x}^ {2}+ {y}^ … Weby = v ± r 2 − x 2 + 2 x u − u 2. This will tell us what y is. There are actually two possible y values for each x. You can see this if you look at a circle. It should also be noted that even though this is correct equation for y, people usually write it in a simpler way.
