First we compute the distance between the center and the given point which is exactly the radius
r =

Now that we know the center and the radius, we can write the equation of a circle with given radius and center:

where (h,k) represent the coordinates of the center (3,7).
We substitute and obtain

Answer:
1) B. -2 hours per person
2) C. 3.60 per pound
Step-by-step explanation:
1)
We can make a slope triangle connecting the points (4, 12) and (10,0)
We get -12/6, or -2 as our slope & final answer
2)
You can do x/y to find the unit rate for this one, or in this case 18/5 = 3.6

to find a coterminal angle, just add or subtract 360°. so you could use -300° or 420°.
Maybe just leave it and ask about it later
