Answer :

The standard equation of a circle can be wriiten as;

[tex](x-h)^2+(y-k)^2=r^2[/tex]

So, to get the value of h,k and r we need to express the given equation in this form.

The equation is given as;

[tex]x^2+y^2-6x+2y+9=0[/tex]

Then we will try to express this equation in the standard equation of circle form.

[tex]x^2-6x+9+y^2+2y+1=1[/tex]

Note that we added 1 to both sides so that we can factorise the equation.

Factorizing, we have;

[tex](x-3)^2+(y+1)^2=1[/tex]

Then finally we have;

[tex](x-3)^2+(y-(-1))^2=1^2[/tex]

Comparing the equation to the standard form we have;

[tex]\begin{gathered} h=3 \\ k=-1 \\ radius\rightarrow r=1 \end{gathered}[/tex]

Then lastly we need to graph the equation;

From the graph, we can see that the only intercept we have is at;

[tex]\begin{gathered} x=3 \\ \text{ point }\rightarrow(3,0) \end{gathered}[/tex]

There is no intercept on the y axis.
