Answer:
Option C 
Step-by-step explanation:
step 1
Find the radius of the circle
we know that
The distance from the center of the circle to any point on the circumference of the circle is equal to the radius of the circle
we have
(1,-1) and (5,7)
the formula to calculate the distance between two points is equal to

substitute the values



step 2
Find the equation of the circle in center radius form

where
(h,k) is the center
r is the radius
substitute

Answer:
y = 600x + 3659
Step-by-step explanation:
General form of the linear equation:
y = mx + b
Given :
x = 0 represents 1992
x = 0 , y = 3659
So, x value for 1997 becomes:
x = 1997-1992 = 5
at x = 5, y = 6659
Plugging in x = 0, y = 3659 in y = mx+b
3659 = m(0) + b
b = 3659
Plugging in x = 5, y = 6659 and b = 3659
6659 = m(5) + 3659
Solving for m:
m(5) = 6659-3659
5m = 3000
m = 3000/5 = 600
Now plug in the values of unknowns m and b in general equation:
y = 600x + 3659
150 grams because 5 oz is equal to 141 grams
