The standard form of a circle is:

Your center is
and your radius is 
Plug them into the equation and you get


The correct answer is D.
Well on a table of data, if the y coordinates increase a lot over a short x distance then it will be steep.
In an equation, you would put it into y = mx + b form and whatever your m is will be your slope. If m is large, it will be steep.
I would say 2 1/3
