Answer:
who?
Step-by-step explanation:
The equation of a circle is:
(x-h)2 + (y-k)2 = r2
where (h,k) is the location of the center and r is the radius. So we need to find h, k, and r. The center is given as (5,-4) so h = 5 and k = -4:
(x-5)2 + (y-(-4))2 = r2
(x-5)2 + (y+4)2 = r2
So we need to find r. Use the distance formula to find the distance between (5,-4) and (-3,2):
r = [(5-(-3))2+((-4)-2)2]1/2
r = [82 + (-6)2]1/2
r = [64 + 36]1/2
r = 1001/2
r= 10
The final equation is:
(x-5)2 + (y+4)2 = 102

That's the answer on edge!
Answer:
6 but read the note below.
Step-by-step explanation:
When the equation has one y on one side of the equal sign, and x on the other side (as you have), the slope is the number to the left of the x.
The slope = 6
1. 4/7
2.1/2
3.4/15
4.50/3
5. 6
6. 9
When you multiply the fraction just multiply denominator with denominator and numerator with numerator
