What is the equation of the circle with center (0, 0) that passes through the point (–6, –6)?

Explanation:

The equation of a circle of center(a,b) and radius r is :

(

x

−

a

)

2

+

(

y

−

b

)

=

r

So,to think about the equation of a circle we should think about its center and radius .

The center is given (0,0).

The circle passes through the point (1,-6) so ,

the radius is the distance between (0,0) and (1,-6)

Step-by-step explanation:

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier
