Question

Write an equation for the circle with center (-4, 4) and containing the point (-1, 16). Use the ^ key for the exponents. Write your answer as the example: (x+2)^2+(y-9)^2=100

Answer 1

is the point (-1 , 16) on the circle or within it? i cant tell from your question

Answer 2

within it, i think

Answer 3

(x+4)^2 + (y-4)^2 = r^2 where r^2 > 153

Answer 4

(x+4)^2 +(y-4)^2=153

Answer 5

it said its wrong..

Answer 6

sorry, i should have explained more, 153 is the radius squared, what we do is find the distance between the centre and the point (-1 , 16), and that is the radius

Answer 7

what does it say is the right answer?

Answer 8

it doesnt lol it's a fill in the blank and i cant find it anywhere on the internet

Answer 9

ah is this an online homework? im pretty sure that is the equation for the circle centre (-4, 4) and passing through point (-1 ,16)

Answer 10

yea it is online and i guess so lol
