Question

Dora wrote the equation of the circle in the center radius form as (x − p)2 + (y − q)2 = 16.

The value of p + q is _____.

Answer 1

Hint: The point \((p,q)\) is the center of the circle. (Why is that?)

Answer 2

because it's the radius?

Answer 3

No...

Answer 4

i have no idea. can i have another hint maybe?

Answer 5

Well, knowing \((p,q)\) is the center of the circle is enough for you to figure this out. The general form of the circle \(x^2+y^2=r^2\) becomes your equation when you translate it right by \(p\) units and up \(q\) units. (Then, separately, applying the right value of radius \(r\)).
