Question

find the standard equation of every circle that posses through the origin, has radius 5, and such that the Y-coordinate of it's center is -4​

Answer 1

Answer:

x² + (y+4)² = 25

Step-by-step explanation:

Equation of the circle = (x-h)² + (y-k)²= r²

Here, h = 0 , k = -4, r = 5

Substitute,

(x-0)² + (y+4)² = 25

=> x² + (y+4)² = 25
