10-72.

Use what you learned in the previous problem to determine the graph of $x = 1 + 3\cos θ$, $y = 2 + 3\sin θ$.

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

OR

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

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

If $\cos^2 θ + \sin^ θ = 1$, then:

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

What is this the graph of?
