The equation of a circle is given below.
What is its center?

Answer:
[tex]( \frac{2}{3}, 0)[/tex]
Step-by-step explanation:
The general equation for a circle is
[tex]{(x - a) }^{2} + {(y - b) }^{2} = {r}^{2} [/tex]
Where a and b are the x and y values of the centre. So comparing to your equation you can see that a is 2/3 and b is 0
