Consider the equation $(x-5)^2+(y-8)^2=49$.

1. What can you tell about the graph just by looking at the equation?

   Hint (a):

   Notice that both $x$ and $y$ are squared.

   Answer (a):

   This is a circle with center $(5,8)$ and radius $7$.

2. Sketch a graph of $(x-5)^2+(y-8)^2=49$.

   Show Graph (b):
