Question

Graph the equation ( x – 1)2 + ( y – 2)2 = 9. Name the center and the radius.
Answer choices: a. (-1, -2) r = 3
b. (1,2), r = 3
c. (2,1), r = 3
d. (-1,-2) r = -3

Answer 1

the standard form for the equation of a circle is:
(x-h)^2 + (y-k)^2 = r^2

where (h,k) is your center and r is your radius.

Answer 2

i got -1,-2 r=3 what did u get
