Answer: negative ; -144 sowwy if im wrong
Step-by-step explanation:
-4, 2, -3 , 6
-4 times -3 = -12
6 times 2 = 12
-12 times 12 = -144
The point-slope form:

- given point
- given slope
The standard form:

<em>use distributive property</em>
<em>add
to both sides</em>
<em>subtract
from both sides</em>
<em>change the signs</em>

Answer:
Center: (-1,8)
Radius: 1
The graph is attached.
Step-by-step explanation:
The equation of the circle has the form:

Where (h,k) is the point of the center of the circle and r is the radius of the circle.
The equation given in the problem is

Therefore:
h=-1
k=8
Then, the center is (-1,8) and radius is 1.
You can graph the circle with its center at the (-1,8) and a radius of 1 as you can see in the figure attached.
9=m-4
9+4=m
13=m
9=13-4
9=9
I hope this answer helped you!!! Thank you!!!
