Answer 2

Remembering the form \((x-h)^2 + (y-k)^2 = r^2\) where the center coordinate is (h,k), can you tell me the center coordinates of the two circles?

Answer 3

im not sure how to find it

Answer 4

Can you tell me what the h and k's are? Just flip the sign of the numbers after x and y

Answer 5

h and k is the center?

Answer 6

yes, but I want the numbers of h and k

Answer 7

5,4 and 3,5

Answer 8

which ones have the negative sign?

Answer 9

5 and 5

Answer 10

wrong

flip all of the signs, positive becomes negative, the negative becomes positive, because we are not adding x and y to h and k, we are subtracting

Answer 11

4 and 3

Answer 12

Yes the coordinates are
(5,-4) and (-3,5)

now you just need to find the equation of a line that goes through these two points
first find the slope, then the y intercept

do you know how to do that?

Answer 13

yes i think

Answer 14

alright, tell me when you get the answer

Answer 15

-9/8

Answer 16

yes, that is the slope

Answer 17

how about the y intercept?

Answer 18

is it y=mx+b

Answer 19

yes

Answer 20

y=-9/8x+13/8

Answer 21

yes, good job

Answer 22

thats the answer?

Answer 23

well, there are three ways to write a linear equation
standard form is ax + by =c
if you want to convert it to that, go ahead
but your equation will probably work

Answer 24

let me see

Answer 25

then convert it to standard form then i guess

Answer 26

9x+8y=13?

Answer 27

snowflake

Answer 28

yeah

Answer 29

it worked thanks
