A).
.
It is difficult to discern your equation.
If this is not your equation, clarify it and re-post your question.
.
%28x-1%29%5E2%2B%28y-3%29%5E2=0
.
Point (-1,1)
x=-1, y=1
Put these values in the equation, and evaluate to see if it is true.
.
%28%28-1%29-1%29%5E2%2B%281-3%29%5E2=0
-2%29%5E2%2B%28-2%29%5E2=0
4%2B4=0
8=0 . False. The point is not on the graph.
.
B).
x intercept: y=0
.
%28x-1%29%5E2%2B%28y-3%29%5E2=0
%28x-1%29%5E2%2B%280-3%29%5E2=0
%28x-1%29%5E2%2B%28-3%29%5E2=0
%28x-1%29%5E2%2B9=0
%28x-1%29%5E2=-9
sqrt%28%28x-1%29%5E2%29=sqrt%28-9%29
x-1=+/-3i
x=1%2B3i OR x=1-3i
No x intercept.
.
y intercept: x=0
.
%28x-1%29%5E2%2B%28y-3%29%5E2=0
%280-1%29%5E2%2B%28y-3%29%5E2=0
%28-1%29%5E2%2B%28y-3%29%5E2=0
1%2B%28y-3%29%5E2=0
y-3%29%5E2=-1
sqrt%28%28y-3%29%5E2%29=sqrt%28-1%29
y-3=+/-i
y=3%2Bi OR y=3-1
No y intercept.
.
Graph of the equation is a circle with center at (1,3) and zero radius.
The only real number solution is point (1,3).
