Austin wants to sketch the graph of a circle represented by the given equation. (x - 4)2 + (y + 7)2 = 64 
Using complete sentences, describe the steps used to sketch the circle on a coordinate grid.

anonymous · Answer

according to your given... do you know 
where Center is and what dimension radius has? :)

anonymous · Answer

no how do u find that out agein?

anonymous · Answer

i really have no idea how to do this i dont understand it at all

anonymous · Answer

$$\LARGE (x-h)^2+(y-k)^2=r^2$$

Center (h,k)   Radius  (r)

anonymous · Answer

radius would be 64 and center would be (4,7) then right?

anonymous · Answer

or would the senter be (-4,7)?

anonymous · Answer

not actually... in your case you have:
$$\LARGE (x-4)^2+[y-(-7)]^2=8^2$$
so Center is  4,7  and radius 8

anonymous · Answer

oh alright

anonymous · Answer

sorry Center is 4,-4 ... and radius 8 :)

anonymous · Answer

AHAHAHAHAHAHAHAAHAHHAA......


sorry Center is 4,-7 ... and radius 8 :)
I'm in hurry... typo mistake .. lol

anonymous · Answer

all good lol

anonymous · Answer

ok .. now let's start sketching... we know that center is 
C(4.-7)

which means x=4  and y=-7

... and this looks like:

|dw:1335793963064:dw|
so center of the circle is at point P.
