    Equation in complex notation

    Not sure if this is the correct forum, but here goes...

    Write the equation of the given circle or straight line in complex notation:

    a) The straight line through 1 and -1-i

    b) The vertical line containing -3-i

    c) The circle through 1, i and 0

    I don't necessarily need you guys to work these out for me. I assume there must be formulas to following when working with lines and circles but I can't find anything in my notes or book. Please HELP!! Thanks.

    Remember that a complex number z is written as x + iy.

    So treat the real part of each complex number as the x value and the imaginary part of each complex number as the y value.

    Then you can use the standard methods that you should already be familiar with.
