With that you can fill in the standard equation of a circle:

Answer:
First you must find the slope So look on your craft and go over to X and look at where y is looking at why count how many up right or left x is then you will have the slope the slope is always rise over run so how far up and then how far over your why is always gonna be your B so basically you would have a Y=B-x
