Distance from (-2,3) to (-1,1)

[nukeman]

Homework Statement

Find the distance from the point (-2,3) to the centre of the circle x^2 + 2x + y^2 - 2y - 3 = 0

Homework Equations

The Attempt at a Solution

The circle, I calculated that the center point is (-1,1) is that correct?

Then, I just input it into the distance formula: √(-1+2)^2 + (1 - 3)^2

?
