    Locus question #2

    Hi again, i have another locus problem, this time:

    Find the equation of the locus of a point P(x,y) that moves so that the ratio of PA to PB is 3:2, where A=(-6,5) and B=(3,-1)

    Find, using the distance formula the magnitude of PA and PB in terms of x and y. Set up an equation such that the ratio of PA to PB is always 3 to 2.
