It should be C., is that what the graph looks like?
Please find attached photograph for your answer. Hope it helps. Answer is option B. 71°.
The circumference of a circle with radius
is

So, one quarter of a circumference will be

You radius is 6, so we have

Answer: y-1=6(x+7)
Step-by-step explanation:
The formula for point-slope form is
. Since we are given the point and slope, we can directly plug them in.
[distribute by -1]

Now, we know that the point-slope form is y-1=6(x+7).
