Question 1077799
Write the equation of the circle with center (-4, 11) and containing the point (5, -1). Use the ^ key for the exponents.


Write your answer as the example: (x+2)^2+(y-5)^2=49
<pre>Equation of a circle: {{{(x - h)^2 + (y - k)^2 = r^2}}}
{{{(5 - - 4)^2 + (- 1 - 11)^2 = r^2}}} ------- Substituting (5, - 1) for (x, y), and (- 4, 11) for (h, k)
{{{matrix(1,9, 9^2 + (- 12)^2 = r^2, "=====>", 81 + 144, "=", r^2, "=====>", 225, "=", r^2)}}}
{{{highlight_green((y + 4)^2 + (x - 11)^2 = 225))}}} ------- Substituting (- 4, 11) for (h, k), and 225 for {{{r^2}}}
