## Homework Statement

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

## 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

?

What's you question?

Is the point, (-2,3), on the circle? ... just asking?
