Question

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

Answer 1

Draw a circle with center `(0.1)` and radius `1`

Explanation:

`(x-x_1)^2+(y-y_1)^2=r^2` is the equation of a circle with center `(x_1,y_1)` and radius `r`.

As `x^2+(y−1)^2=1` can be written as `(x-0)^2+(y-1)^2=1^2`,

we have to draw a circle with center `(0.1)` and radius `1`.
