# How do you graph x^2+(y-1)^2=1?

Draw a circle with center $\left(0.1\right)$ and radius $1$
${\left(x - {x}_{1}\right)}^{2} + {\left(y - {y}_{1}\right)}^{2} = {r}^{2}$ is the equation of a circle with center $\left({x}_{1} , {y}_{1}\right)$ and radius $r$.
As x^2+(y−1)^2=1 can be written as ${\left(x - 0\right)}^{2} + {\left(y - 1\right)}^{2} = {1}^{2}$,
we have to draw a circle with center $\left(0.1\right)$ and radius $1$.
