The equation of a circle is just (x-h)^2+(y-k)^2= r^2
in place of h you just put the x-coordinate of the center
in place of k you put the y-coordinate of the center
and in place of r you put the radius
So your answer is just (x-1)^2+(y-4)^2=4 (first choice)
The answer for the first one is B 56 and for the second it's and unless you meant 80 for C none of them are correct.
B. Collinear
Collinear means that two or more points are on the same line.
The answer would be 1,872 because you add the deposits and then subtract the withdrawals
