10-72.

If you are stuck, make a table with θ, x, and y. Then plot each (x, y,) point.

OR

$cos\;\theta=\frac{\textit{x}-1}{3}$

$sin\;\theta=\frac{\textit{y}-2}{3}$

If cos² θ + sin² θ = 1, then:

$\left( \frac{\textit{x}-1}{3} \right)^2+\left( \frac{\textit{y}-2}{3} \right)^2=1$

What is this the graph of?
