Question

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

Answer 1

\( \color{Black}{\Rightarrow (x - h)^2 + (y - k)^2 = r^2 }\)

Compare the equation.
(h,k) is the center.
r is the radius.

Answer 2

What is the vaule of p + q?

Answer 3

Can you tell me what the center is here?

Answer 4

(p,q) are the center co-ordinates.

Answer 5

1,3 is the center

Answer 6

Exactly.... so what is 1 + 3?

Answer 7

4

Answer 8

:) that's it...that's the answer

Answer 9
