Write The Equation Of The Circle In General Form Show Your Work SOS class=

Sagot :

Answer:

The equation of the circle is

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

where (h,k) is the center and r is the radius.

The center is (-1,1) so plug that in the equation.

[tex](x - ( - 1)) {}^{2} + (y - 1) {}^{2} = {r}^{2} [/tex]

[tex](x + 1) {}^{2} + (y - 1) {}^{2} = {r}^{2} [/tex]

The radius of the circle is 3 so plug that in for r.

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

[tex](x + 1) {}^{2} + (y - 1) {}^{2} = 9[/tex]
