Given the equation x^2 +y^2+8y65=0
(a) Write the equation in standard form.
(b) State the center, radius, and intercepts.
(c) Submit the graph

rearrange terms to complete the squares:
x^2 + (y^2 + 8y + 16) = 65 + 16
x^2 + (y+4)^2 = 9^2
center: (0,4)
radius: 9
yintercepts: (0,13) and (0,5)
xintercepts: (√65,0) and (√65,0)
