Question

Look at the graph.



Which equation best represents the circle in the graph?

(x + 1)^2 + (y - 2)^2 = 25

(x + 1)^2 + (y + 2)^2 = 25

(x – 1)^2 + (y - 2)^2 = 25

(x – 1)^2 + (y + 2)^2 = 25

Answer 1

@Euler271 Thank you!!!

Answer 2

glad i could help :)

Answer 3

correcting:

general equation:

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


with the center at (h,k) and radius r.


The center in the graph is in the 2nd quadrant. Meaning that x is a negative number as y is a positive number.

this means that we are dealing with (x + )^2 and (y - )^2
