What is the center of the circle described by the equation (x - 2)^2 +(y + 7)^2 =169
A (2, 7)
B (-2, -7)
C (2, -7)
D (-2, 7)

Sagot :

Answer:

The center is (2, -7)

Step-by-step explanation:

A circle is given by

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

where(h,k) is the center and r is the radius

(x - 2)^2 +(y + 7)^2 =169

(x - 2)^2 +(y -  -7)^2 =13^2

The center is (2, -7) and the radius is 13
