Question

Write the standard equation of the circle in the graph.

A. (x + 3) + (y – 2) = 9

B. (x – 3)2 + (y + 2)2 = 9

C. (x – 3)2 + (y + 2)2 = 18

D. (x + 3)2 + (y – 2)2 = 18

Answer 1

ok! I can explain! its b! since you the center is (3,-2) and radius is approx. 2.5

Answer 2

actually radius is 3!

Answer 3

so...you just square it! and find the negative of the centers! to put it in standard format!

Answer 4

You shoul remember this:
\[(x-x_1)^2+(y-y_1)^2=r^2\]
Where (x1,y1) is the center
r is the radius.

Answer 5

thanks
