Question 1168433

The center is at (1, -3) and the passes through (-3, 5). Find the equation of the circle.
<pre>Equation of a circle: {{{matrix(5,3, (x - h)^2 + (y - k)^2, "=", r^2, (- 3 - 1)^2 + (5 - - 3)^2, "=", r^2, (- 4)^2 + (8)^2, "=", r^2, 16 + 64, "=", r^2, 80, "=", r^2)}}}
           Equation: {{{highlight_green(matrix(1,3, (x - 1)^2 + (y + 3)^2, "=", 80))}}}
