Which equation represents a circle with the same radius as
the circle shown but with a center at (-1.1)?
(x - 1)2 + (y + 1)2 = 16
(x - 1)2 + (y + 1)2 = 4
O (x + 1)2 + (-1)2 = 4
(x + 1)2 + (y-1)2 = 16
its a timed quiz so please, please help.

Answer :

and

Step-by-step explanation:

Given : A circle with the same radius as  the circle shown but with a center at (-1.1).

To find : Which equation represents a circle ?

Solution :

The equation of a circle with center (h,k) and radius r is given by :

Here, we are given (h,k)=(-1,1)

and radius r=4 units

So, equation of circle will be :

or

Therefore, the required equations of circle are

and

how am i supposed to answer

step-by-step explanation:

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
