Acircle is centered at the point (5, -4) and passes through the point (-3, 2).
the equation of this circle is (x +_ )2 + (y +_ )2 = _

The answer to your question is    (x - 5)² + (x + 4) = 100

Step-by-step explanation:

Data

Center = (5, -4)

Point = (-3, 2)

Process

1.- Calculate the length of the radius

Formula

      d =

Substitution

     d =

Simplification

     d =

     d=

     d =

     d = 10

2.- Get the equation of the line

     h = 5    k = -4    r = 10

     ( x - 5)² + (y + 4)² = 10²

Simplification and result

                               (x - 5)² + (x + 4) = 100
