Question

LAST ONE! (:

Answer 1

remember the equation:
(x-h)^2+(y-k)^2=r^2

Answer 2

in this case, you do not need the radius like the last one. in this one you need the centre
given by (h,k)

Answer 3

so is h and k 4 and 3?(:

Answer 4

check the signs

Answer 5

4 sq. and 3 sq. ? (:

Answer 6

or is it -4? (: I cant tell but they come out as16 + 9

Answer 7

no.
in the equation
(x-h)^2+(y-k)^2=r^2
the centre is (h,k)
when it is taken out of the brackets, the sign changes

Answer 8

you don't need to do any extra work, the answer is already in the equation, you just need to know how to find it
