What Is The Center Of A Circle Represented By The Equation { (x+9) 2+(y-6) 2=10^2$}$?A. { (-9, 6)$}$ B. { (-6, 9)$}$ C. { (6, -9)$}$ D. { (9, -6)$}$

The equation of a circle in standard form is given by $(x-h{)}^2+(y-k{)}^2=r^2$(x-h)^2+(y-k)2=r^2}, where ${(h,k)$ represents the center of the circle and $r$r} is the radius. In this article, we will explore the equation ${(x+9)2+(y-6)2=10^2$ and determine the center of the circle.

Breaking Down the Equation

To find the center of the circle, we need to identify the values of ${h}$ and ${k}$ in the equation. The given equation is ${(x+9)^2+(y-6)^2=10^2}$. By comparing this equation with the standard form, we can see that ${h=-9}$ and ${k=6}$.

Why is this the Center of the Circle?

The center of a circle is the point that is equidistant from all points on the circle. In other words, it is the point that is at the center of the circle. To verify that ${(-9,6)}$ is indeed the center of the circle, we can substitute these values into the equation and check if it satisfies the equation.

Substituting the Values

Let's substitute ${x=-9}$ and ${y=6}$ into the equation ${(x+9)^2+(y-6)^2=10^2}$.

${(x+9)^2+(y-6)^2=10^2}$ ${(-9+9)^2+(6-6)^2=10^2}$ ${0^2+0^2=10^2}$ ${0=100}$

However, this is not true. The equation does not satisfy when we substitute the values of the center. This is because the equation is not in the standard form. The equation is actually in the form ${(x-h)^2+(y-k)^2=r^2}$, where ${r=10}$ and ${h=-9}$ and ${k=6}$.
