#### Answer:

The equation is

#### Explanation:

As a circle is a point that moves so that its distance from a given point (called center) is always same (called radius), we should first calculate the distance of a point

Hence

Now squaring both sides, we get

graph{x^2+y^2-16x-14y+77=0 [-20, 20, -5, 15]}
