Question

If the equation of a circle is (x + 4)2 + (y - 6)2 = 25, its center point is



(4, 6)

(-4, 6)

(4, -6)

Answer 1

(x-a)^2+(y-b)^2=r^2 where (a, b) is the center

Answer 2

\(\LARGE\color{slate}{ (x -\color{red}{h})^2 + (y - \color{green}{k})^2 = \color{blue}{r}^2 }\)
is the formula.



where:

\(\LARGE\color{slate}{ (\color{red}{h},\color{green}{k}) }\) is the center.

\(\LARGE\color{slate}{\color{blue}{r} }\) is the radius.

Answer 3

so -4,6?

Answer 4
