Answer:
i think it is A, C, OR B, **For the first equation**
Step-by-step explanation:
SRRY IF WRONG!
X=3.5 add 10 and divide by 8
the slope is -12 because y=mx+b and m= slope
Answer:
The radius is 12.
Step-by-step explanation:
You're given the center and a point on the circle. The point and the center both have an x-coordinate of -5, so there is no horizontal distance between them. The distance is only in the vertical direction. The distance from 8 to -4 is 12. Since this is the distance from the center to a point on the circle, this equals the radius.
