Write the equation in standard form for the circle that has a diameter with endpoints (6, -9)

nevsk [136]

Answer:

Step-by-step explanation:

By definition a diameter goes through the center of the circle. So if we find the midpoint of the diameter, we will have the h and k of the center. Then we will use one of the points ON the circle as x and y and solve for r. Here goes:

$M=(\frac{6+(-6)}{2},\frac{-9+(-9)}{2})$ to get a midpoint/center of (0, -9).

The standard form of a circle is

$(x-h)^2+(y-k)^2=r^2$

Filling in with h, k, x, and y:

$(6-0)^2+(-9-(-9))^2=r^2$ which simplifies to

$6^2+0^2=r^2$ so

$r^2=36$

Now we can write the equation of the circle:

$x^2+(y+9)^2=36$
