Answer:

(x + 1)^2 + (y - 1)^2 = 74.

Explanation:

The center is at (-1, 1) and a point in the line is (6, -4)

The general formula is

(x - h)^2 + (y - k)^2 = r^2 where (h, k) is the center and r = the radius.

Here h = -1, k = 1 and a point on the line is (6, -4)

(6 - (1))^2 + (-4 - 1)^2 = r^2

r^2 = 49 + 25 = 74

So the equation is

(x + 1)^2 + (y - 1)^2 = 74
