Question

Write the equation of the circle centered at ( - 4,7) with radius 20?

Answer 1

(x + 4)² + (y - 7)² = 20²

Explanation:

Graphing form

(x - h)² + (y - k)² = r²

(h, k) is the center = (-4, 7)

r is the radius = 20

-----------------------------------

Plug in the givens

(x + 4)² + (y - 7)² = 20²
