Answer:
The center of the circle is

Step-by-step explanation:
Let the equation of the circle be
, where (-a,-b) is the center of this circle.
The points lying the circle must satisfy the equation of this circle.
A(0,0)
We substitute this point to get;


B(-3,0)



But c=0


C(1,2)



Put the value of 'a' and 'c' to find 'b'




b=-2
Hence the center of the circle is

There are 8 sets of 21 cups in 168 cups so 9 times 8 is 72
(-3,7)
5(-3)+2(7)=-1
-15+14=-1
Answer:The answer is C
Step-by-step explanation:
You need to use the slop formula (y2-y1/x2-x1)
9 -3/5--3
6/5+3
6/8
3/4
The slope is 3/4
