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

    1. The problem statement, all variables and given/known data

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


    2. Relevant equations



    3. 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?
