Question

What is the standard form of the equation of a circle with its center at (2, -3) and passing through the point (-2, 0)?

Answer 1

\[\huge\rm (\color{blue}{x}-\color{red}{h})^2 + (\color{blue}{y}-\color{ReD}{k})^2 = r^2\]
here (h,k) is the center \[\color{reD}{(2,-3)}\]
and point \[\rm \color{blue}{(-2,0)}\] are x and y values so substitute values solve for r
