Question

The equation of a circle is (x - 4)2 + (y + 3)2 = 36. Where is (2, -1) located in relation to the circle?

Answer 1

Plug it into the equation of your circle and compute it:
\[\Large x=2 \\ \Large y=-1 \]

Answer 2

so the answer for (x - 4)2 + (y + 3)2 = 36 is x = 2 and y = -1?

Answer 3

located in relation to the circle??? wat doea that mean? ummm to the left of the circle? >.>

Answer 4

@HawkCrimson, there is ON the circle, INSIDE the circle, and OUTSIDe the circle.
I believe that's what they are looking for here.

Answer 5

yeah im looking for if it would be on the circle, inside, outside, or the center of the circle.

Answer 6

oh lol then sub in x = 2 and y = -1 and if the left and right side of the equal sign r both 36 (like this, 36 = 36) then the coordinates would be on the circle :)

Answer 7

then 4 + 4 = 8 and now u have 8 = 36 which means that the point isnt on the circle

Answer 8

its outside the circle then

Answer 9

or inside

Answer 10

okay thank you for the help!

Answer 11

ur welcome :)
