Answer:

(x +4)^2 +(y +8)^2 = 64

Step-by-step explanation:

The equation of a circle with center (h, k) and radius r is ...

(x -h)^2 +(y -k)^2 = r^2

The circle centered at (h, k) = (-4, -8) with radius 8 has equation ...

(x +4)^2 +(y +8)^2 = 64

Answer:

second option

G(3 , -4) ; H(8 , 1)

Step-by-step explanation:

For the line GH to be a median, the point G must have the intermediate value at x and at y between points A and B, and the point H must have the intermediate value at x and at y between points A and B

G = (Ax + Bx)/2 , (Ay + By)/2

G = (3 + 3)/2 , (-9 + 1)/2

G = 6/2 , -8/2

G = (3 , -4)

H = (Cx + Bx)/2 , (Cy + By)/2

H = (13 + 3)/2 , (1 + 1)/2

H = 16/2 , 2/2

H = (8 , 1)

This is because for a medium to be the point p has to be right in the middle of the other 2 vertices
