Answer:
(x+1)^2+(y-7)^2=8
Step-by-step explanation:
You should try the next one and I can check work or tell you if it is right.
The diameter length can be found be computing the distance that (-3,5) is to (1,9) which is sqrt(4^2+4^2)=sqrt(32).
The radius is half the diameter so it is sqrt(32)/2.
The center of the circle is the midpoint of a diameter. So compute the (Average of x, average of y)=(-1,7)
So plug into (x-h)^2+(y-k)^2=r^2 we get
(x+1)^2+(y-7)^2=32/4
simplifying gives
(x+1)^2+(y-7)^2=8

Answer:
k = 5
Step-by-step explanation:
y = kx
15 = k(3)
k = 15/3
k = 5
Answer:
x>7
-6x+14< -28
-14. -14
-6x<-42
÷-6 ÷-6
x<7
switch signs because we divided by a negative number
x>7
Answer: x<-1
3x+28<25
-28 -28
3x<-3
÷3 ÷3
x<-1
