Explained below

#### Explanation:

The given equation represents a circle centered at (2, -1) and radius equal to $\sqrt{13}$. First locate the point (2, -1) on the graph and the next task is to measure a radius equal to $\sqrt{13}$. For this draw a right triangle with sides 12 and 5 units. Then with radius equal to the hypotenuse draw the required circle using (2, -1) as the center using compass.
