(x-h)^2+(y-k)^2=r^2
(h,k) is center
r=radius
(x-2)^2+(y-(-3))^2=2^2
center is (2,-3)
radius is 2
A. (2,-5) is on the circle, not inside
B. (2,-4) is inside
C. (0,-3) is on the circle, not inside
D. (2,0) is on the circle, not inside
answer is B
Answer:
Step-by-step explanation:
To be parallel the slopes must be equal
4x-3y=15
3y=4x-15
y=(4x-15)/3
so m=4/3
Only line D. has a slope of 4/3
Answer:
slope 3
Step-by-step explanation:
-2+y=4
4+y=10
10+y=16
y= 6
0+x=2
2+x=4
4+x=6
x=2
slope= change in y/ change in x
6/2=3
Answer:
c
Step-by-step explanation:
we have to use a mean to describe the center
