Question Find the equation of the circle with center at (1,-1) and passing through (-2,3).

Studdy Solution
Simplify the equation by squaring the radius.
$$(x - 1)^2 + (y + 1)^2 = 25$$
The equation of the circle with center at $(1,-1)$ that passes through $(-2,3)$ is:
$$(x - 1)^2 + (y + 1)^2 = 25$$
