Answer:
Step-by-step explanation:
Answer:
Option C.
Step-by-step explanation:
Note : In the given points one point is (8,-2) instead of (-6,-2).
The standard form of a circle is
where, (h,k) is center of circle and r is radius.
It is given that center of the circle is (-1,-2). So,
...(1)
It is given that the circle passing through the point (8,-2),(-1,5),(6,-2),(-1,-9).
Substitute x=6 and y=-2 in equation (1).
Substitute
in equation (1).
Therefore, the correct option is C.
- 5 and -4 are coefficients, so the product is (-5)(-4) = 20
1+2= 3, this gives us 4=3-1/4w, subtract 3 on both sides is, 1=1/4w, divide 1/4 on each side. ANSWER: 4
