I think I can help you

Answer 2

ok

Answer 3

what is the standard form of a circle

Answer 4

did you find it?

Answer 5

25

Answer 6

what is 25? that doesn't seem like an equation

Answer 7

here's what I was looking for:
(give me a second to write it out)

Answer 8

\[(x - h)^{2} + (y-k)^{2} = r^{2}\]

Answer 9

where the center is (h,k) and the radius length is r

Answer 10

I don't know I suck

Answer 11

that's not true you can do this

Answer 12

you said the center is the origin right? what are the coordinates for the origin

Answer 13

@hleper what are the coordinates of the origin?

Answer 14

10

Answer 15

not quite.

Answer 16

it should look like (x,y)

Answer 17

at least put some sort of effort into it.

Answer 18

the numbers x and y indicate how far up or down on the y axis and how left or right on the x axis the point is.

Answer 19

if you are at the origin you don't move up, down, left, or right at all, so you are at 0 units for both x and y.
can you write that out?
