A circle is centered at the point (5, -4) and passes through the point (-3, 2).

KATRIN_1 [288]

By definition, the equation of a circle, centered at point (a, b) is

$(x-a) ^ 2 + (y-b) ^ 2 = r ^ 2$

Where r is the radius of the circumference, and is calculated as the distance from the center to any point belonging to the circumference.

We have the center (5, -4) and the point through which the circumference passes (-3, 2), then:

$a = 5\\b = -4\\r = \sqrt {(- 3-5) ^ 2 + (2 + 4) ^ 2}\\r = 10$

Finally, the equation of the circumference is:

$(x-5) ^ 2 + (y + 4) ^ 2 = 10 ^ 2$
